More Details on Our Top Picks

  1. Amazon Smart Thermostat

    Amazon Smart Thermostat

    Best for Easy DIY Setup and Alexa Integration

    View on Amazon

    This thermostat stands out for its straightforward installation process and seamless Alexa compatibility, making it ideal for smart home beginners who want quick setup and voice control. Unlike the ecobee options, which include more advanced sensors and features, the Amazon Smart Thermostat offers a more budget-friendly, basic experience focused on energy savings and DIY ease. However, it requires a C-wire for installation and works solely within the Alexa and Ring ecosystems, limiting flexibility for users invested in other platforms. Its simplicity is a plus for those who prefer minimal setup but a drawback if you want broader smart-home integration or advanced sensors. Overall, this pick makes the most sense for households already using Alexa devices who want straightforward control and energy savings without extra complexity.

    Pros:
    • Easy to install with app guidance
    • Compatible with Alexa for voice control and routines
    • Helps reduce energy bills up to $90 annually
    Cons:
    • Requires a C-wire for installation
    • Limited ecosystem compatibility (Alexa/Ring only)

    Best for: Homeowners seeking simple installation and Alexa voice control, especially those already invested in Amazon’s ecosystem

    Not ideal for: Users with incompatible wiring or those who desire multi-platform compatibility and advanced sensors

    • Compatibility:Works with Alexa and Ring
    • C-wire required:Yes
    • Energy savings:Up to $90 annually
    • Installation:DIY with app guidance
    • Technology:Honeywell Home Thermostat Technology
    Our verdict
    “Best suited for Alexa-centric households looking for an affordable, easy-to-install smart thermostat.”
  2. ecobee Smart Thermostat Premium – WiFi, Siri & Alexa Built-In, Air Quality Monitor

    ecobee Smart Thermostat Premium - WiFi, Siri & Alexa Built-In, Air Quality Monitor

    Best for Premium Features and Air Quality Monitoring

    View on Amazon

    This premium model is designed for users who want not just temperature management but also air quality insights, making it ideal for health-conscious households. Compared with the Sensi Touch 2, which offers solid energy savings and sensor support, the ecobee Premium adds built-in air quality monitoring and a striking design, along with seamless integration with Siri, Alexa, and ecobee’s smart ecosystem. Its higher price point reflects its advanced features, which may be unnecessary for budget-focused users. The included Power Extender Kit simplifies installation, but some features might require additional subscriptions or setup. If you value a sleek design and comprehensive home environment control, this thermostat is a compelling choice.

    Pros:
    • Energy savings up to 26% annually
    • Built-in air quality and occupancy monitoring
    • Seamless voice control with Siri and Alexa
    • Easy DIY installation with included Power Extender Kit
    Cons:
    • Premium price may be a barrier
    • Some features require additional setup or subscriptions

    Best for: Tech-savvy homeowners wanting integrated air quality and voice control with a premium look

    Not ideal for: Budget-conscious users who don’t need advanced air sensors or Siri integration

    • Energy Savings:Up to 26% per year
    • Certification:ENERGY STAR
    • Included Sensor:SmartSensor
    • Compatibility:Most 24VAC HVAC systems
    • Display:Large, vibrant interface
    Our verdict
    “Ideal for users prioritizing advanced home monitoring and premium design in a smart thermostat.”
  3. Sensi Touch 2 Smart Thermostat Wi-Fi, Alexa, Energy Star Certified, ST76

    Sensi Touch 2 Smart Thermostat Wi-Fi, Alexa, Energy Star Certified, ST76

    Best for Flexible Scheduling and Room Sensor Support

    View on Amazon

    This thermostat is a strong choice for those who want balanced temperature control with the option to add room sensors later, making it more adaptable than the ecobee models that include sensors as standard. It offers around 23% energy savings through flexible scheduling, but unlike the ecobee Premium, it requires the purchase of sensors separately. Its DIY-friendly setup and compatibility with Alexa and other smart systems make it accessible, though limited details on its app features could be a drawback for power users. It does not support independent room regulation out of the box, meaning it’s better suited for overall house comfort rather than zoned heating.

    Pros:
    • Energy savings of about 23%
    • Easy DIY installation with app guidance
    • Supports room sensors for flexible temperature control
    • Compatible with Alexa and other smart devices
    Cons:
    • Room sensors sold separately
    • Requires common wire (c-wire) for installation

    Best for: Homeowners interested in adding sensors gradually for better temperature balancing

    Not ideal for: Those needing independent room control without additional purchases

    • Compatibility:Works with room sensors (sold separately)
    • Energy Savings:Approximately 23%
    • Certification:Energy Star
    • Installation:DIY with app guidance
    • Includes:Thermostat, hardware, manual
    Our verdict
    “Great for households looking to enhance comfort with optional room sensors over time.”
  4. TQX Matter Over WiFi Thermostat with Occupancy and Remote Sensor

    TQX Matter Over WiFi Thermostat with Occupancy and Remote Sensor

    Best for Ecosystem Compatibility and Occupancy Sensing

    View on Amazon

    This versatile thermostat supports multiple ecosystems including Alexa, Google, and Apple HomeKit, making it ideal for households with diverse smart home setups. Its occupancy detection and remote sensor support help optimize comfort and energy efficiency, but it doesn’t regulate individual rooms independently, which could be a downside for zoned heating needs. Unlike the ecobee models, it emphasizes broad compatibility and occupancy-based control, though it requires compatible wiring and doesn’t have dedicated room-by-room regulation. Its flexible control options via app, voice, and remote make it suitable for tech-forward households seeking full-house automation.

    Pros:
    • Supports multiple ecosystems (Alexa, Google, Apple HomeKit)
    • Occupancy detection and remote sensors enhance comfort
    • Easy to control via app, voice, or remote
    Cons:
    • Cannot regulate individual rooms independently
    • Requires compatible wiring (C-wire)

    Best for: Smart home enthusiasts wanting broad ecosystem support with occupancy sensing

    Not ideal for: Users needing independent room control or specific zoning

    • Controller Type:Alexa, Android, Apple HomeKit, Google Assistant
    • Features:Auto-scheduling, occupancy detection
    • Connectivity:Wi-Fi, Bluetooth, Zigbee, Matter
    • Power Source:System Powered
    • Display Type:LED
    Our verdict
    “Perfect for users who want broad ecosystem integration with occupancy-based automation, not detailed zoning.”
  5. ecobee Smart Thermostat Essential – WiFi, Energy Star Certified, Compatible with Siri, Alexa, Google Assistant

    ecobee Smart Thermostat Essential - WiFi, Energy Star Certified, Compatible with Siri, Alexa, Google Assistant

    Best for Budget-Friendly Smart Control with Compatibility

    View on Amazon

    This model offers a compelling balance of energy savings and broad smart-home compatibility, making it suitable for those who want reliable basic features without the premium price tag. It supports major voice assistants and can be installed easily without a C-wire, thanks to the optional Power Extender Kit. While it lacks the advanced sensors of the ecobee Premium, it still provides humidity detection and schedule management, making it a practical mid-range choice. The need to purchase additional sensors separately and verify HVAC compatibility means some users might face extra costs or limitations, but overall it delivers solid value for budget-conscious smart home users.

    Pros:
    • Energy savings up to 23% annually
    • Compatible with Siri, Alexa, and Google Assistant
    • Easy DIY installation with optional accessories for no C-wire homes
    • Supports humidity detection and scheduling
    Cons:
    • SmartSensor and Power Extender Kit sold separately
    • Limited advanced features compared to premium models

    Best for: Homeowners seeking a cost-effective, versatile smart thermostat with broad voice assistant support

    Not ideal for: Users wanting integrated air quality monitoring or advanced sensor features

    • Energy Star Certified:Yes
    • Compatibility:Most 24 VAC HVAC systems
    • Control:Color touchscreen, app, voice
    • SmartSensor:Optional, sold separately
    • Installation:DIY with Power Extender Kit
    Our verdict
    “Best for budget-conscious households wanting reliable smart control and broad compatibility.”
  6. ecobee Total Security and Savings Bundle with Smart Thermostat Premium

    ecobee Total Security and Savings Bundle with Smart Thermostat Premium

    Best Overall for Integrated Security and Smart Home Control

    View on Amazon

    This bundle stands out for combining the ecobee Smart Thermostat Premium’s advanced climate control with built-in voice assistants and extensive security features. Unlike the Honeywell T9, which focuses solely on room-specific comfort, the ecobee offers a comprehensive home monitoring experience with smoke alarms, activity alerts, and occupancy sensing. However, full security capabilities depend on subscribing to the ecobee Smart Security plan, adding ongoing costs. Its integrated voice assistants simplify daily commands, making it ideal for those seeking an all-in-one smart home hub. The tradeoff is that the security features require professional monitoring for complete functionality, which could be a barrier for budget-conscious users.

    Pros:
    • Built-in Alexa and Siri for seamless voice control
    • Advanced security features like smoke detection and activity alerts
    • Helps reduce heating and cooling costs by up to 26%
    Cons:
    • Requires a subscription to the ecobee Smart Security plan for full features
    • Some security functions may need professional monitoring

    Best for: Homeowners who want an all-in-one smart thermostat and security system with voice control.

    Not ideal for: Users who prefer a simple thermostat without security features or are on a tight budget due to subscription costs.

    • Field of View:Wide, head-to-toe
    • Built-in Features:Alexa, Siri, smoke alarm detection, siren
    • Security Integration:Requires ecobee Smart Security plan
    • Energy Savings:Reduce heating and cooling costs by up to 26%
    • Additional Features:Doorbell live view, radar occupancy sensing, temperature alerts
    Our verdict
    “This pick is perfect for those wanting a premium, security-enabled thermostat that integrates with their smart home ecosystem.”
  7. WiFi Smart Thermostat for Home, Single-Stage 1Heat/1Cool, App Remote Control, 7-Day Programmable

    WiFi Smart Thermostat for Home, Single-Stage 1Heat/1Cool, App Remote Control, 7-Day Programmable

    Best for Simple, Remote-Accessible Climate Control

    View on Amazon

    Compared with the ecobee Premium, this thermostat offers straightforward scheduling and remote control without security extras. Its 7-day programmable schedule makes it ideal for users who want reliable temperature management but don’t need multi-stage or multi-zone features. The requirement for a C-wire limits installation flexibility, especially in older homes, and it lacks the advanced security or sensor support seen in other models like Honeywell T9. It’s a solid choice for those seeking a budget-friendly, easy-to-use smart thermostat that covers basic needs. The main tradeoff is the absence of multi-stage HVAC compatibility and battery power, limiting adaptability for complex systems.

    Pros:
    • Remote control via smartphone app
    • Customizable 7-day schedule
    • Simple, intuitive interface
    Cons:
    • Requires a C-wire for installation
    • Not compatible with multi-stage HVAC systems

    Best for: Homeowners with single-stage systems seeking an affordable, easy-to-program remote thermostat.

    Not ideal for: Users with complex HVAC systems or who prefer battery-powered, wire-free installation.

    • Connectivity:WiFi
    • Compatibility:Single-stage heating and cooling
    • Control:Smartphone app
    • Programming:7-day schedule
    • Wiring:C-wire required
    • Power:No battery operation
    Our verdict
    “Ideal for budget-conscious users who want reliable, remote temperature control without extra complexity.”
  8. Honeywell Home T9 WiFi Smart Thermostat with 1 Smart Room Sensor, Touchscreen Display, White

    Honeywell Home T9 WiFi Smart Thermostat with 1 Smart Room Sensor, Touchscreen Display, White

    Best for Multi-Room Comfort Customization

    View on Amazon

    Compared to the ecobee Premium, the Honeywell T9 emphasizes room-specific comfort through its support for multiple sensors, making it highly suitable for larger or multi-zoned homes. Its touchscreen display enhances usability, and its compatibility with Alexa, Apple HomeKit, and Google Assistant offers flexible voice control options. While it supports a wide range of heating systems, it doesn’t include integrated security features like smoke detection. The main limitation is that it doesn’t work with electric baseboard heat and requires a C-wire or power adapter, which could complicate installation. For those prioritizing targeted comfort over security, this model makes the most sense.

    Pros:
    • Supports multiple sensors for targeted room comfort
    • Remote control via mobile app and voice assistants
    • Easy DIY installation with included power adapter
    Cons:
    • Limited compatibility with electric baseboard heat
    • Requires C-wire or power adapter for installation

    Best for: Homeowners seeking precise control over multiple rooms with easy installation and versatile voice platform support.

    Not ideal for: Users with electric baseboard heating or those looking for built-in security features.

    • Sensor Range:up to 200 ft
    • Compatibility:Forced air, hot water, steam, heat pumps with electric backup
    • Display:Touchscreen
    • Power:C-Wire required, includes power adapter
    • Connectivity:WiFi, Alexa, Apple HomeKit, Google Assistant
    Our verdict
    “Best suited for those wanting multi-room control and flexible smart home integration without additional security features.”
  9. YoLink Thermostat 2, Smart Home & Commercial Thermostat with Dual-Stage Heating & Cooling, Heat Pump Support, External Sensors, Remote App Control, Alexa & Google, LoRa Long Range, Hub Required

    Best for Large Spaces and Long-Range Control

    View on Amazon

    Compared with the Honeywell T9, the YoLink Thermostat 2 offers extraordinary wireless range and support for external sensors, making it ideal for large homes or commercial spaces. Its dual-stage heating and cooling support and heat pump compatibility mirror the ecobee Premium’s advanced features, but the need for a separate hub and C-wire can complicate setup. Its LoRa technology extends the control range to a quarter mile, a significant advantage for sprawling properties. While installation might be complex for DIYers, the ability to control multiple zones and monitor climate remotely makes it a strong choice for extensive installations. The tradeoff is the added cost and complexity of the hub.

    Pros:
    • Extended wireless range up to 1/4 mile
    • Supports external sensors for precise climate management
    • Remote app control and voice assistant compatibility
    Cons:
    • Hub must be purchased separately
    • Requires C-wire for installation
    • Installation complexity for DIY users

    Best for: Large homes or commercial buildings requiring long-range wireless control and external sensor integration.

    Not ideal for: Homeowners seeking a simple, plug-and-play setup or those with small spaces.

    • Dual-Stage Heating & Cooling:Yes
    • Heat Pump Support:Yes
    • External Sensors Support:Up to 2 sensors
    • Wireless Range:Up to 1/4 mile
    • App Control:Yes
    • Voice Control:Alexa & Google
    • Hub Required:Yes
    Our verdict
    “Ideal for large properties needing extensive wireless control and external sensor support, despite added setup complexity.”
  10. Sensi Smart Thermostat, Wi-Fi, DIY, Alexa, Energy Star Certified, ST55

    Sensi Smart Thermostat, Wi-Fi, DIY, Alexa, Energy Star Certified, ST55

    Best for Easy DIY Installation and Energy Savings

    View on Amazon

    Compared with the ecobee and Honeywell models, the Sensi ST55 offers straightforward installation designed for DIYers, making it accessible for those intimidated by complex wiring. Its energy savings of about 23% make it a practical choice for budget-conscious users aiming to cut HVAC costs. While it lacks the multi-sensor support or advanced security features of the ecobee bundle, its compatibility with major smart home platforms ensures flexible remote control. The main tradeoff is that it offers fewer customization options and may not support multi-zone configurations as seamlessly as higher-end options. This makes it best suited for simple setups where ease of installation and reliable basic control are priorities.

    Pros:
    • Easy DIY installation with step-by-step instructions
    • Energy savings of approximately 23%
    • Compatible with Alexa, Google Assistant, and Apple HomeKit
    Cons:
    • Requires a common wire in some setups
    • Limited customization compared to premium models

    Best for: DIY homeowners seeking an easy-to-install, energy-efficient thermostat with broad smart platform compatibility.

    Not ideal for: Users needing multi-zone control, advanced security, or complex customization features.

    • Controller Type:Amazon Alexa, Apple HomeKit, Google Assistant, SmartThings, Vera
    • Additional Features:Data Privacy, Easy DIY Install, Energy Savings, Filter Indicator, Programmable
    • Specific Uses:Air Conditioner, Boiler, Furnace, Heat Pump
    Our verdict
    “Best suited for DIY enthusiasts wanting simple, reliable smart control with good energy savings.”
  11. Honeywell Home X8S Premium Smart Wi-Fi Thermostat with Sensor

    Honeywell Home X8S Premium Smart Wi-Fi Thermostat with Sensor

    Best Overall for Advanced Multi-System Control

    View on Amazon

    The Honeywell Home X8S stands out for its extensive compatibility and integrated sensors that provide precise room-by-room comfort. Unlike the Ecobee Smart Thermostat Premium, which includes an air quality monitor, the X8S emphasizes HVAC flexibility and energy savings, making it ideal for those managing complex systems. Its 5-inch touchscreen offers intuitive control, while support for Alexa, Google, and Apple ecosystems broadens smart home integration. However, it requires a C-wire or the included adapter, which could complicate installation in older homes. Its remote sensors are effective up to 200 feet, but electric baseboard heat isn’t supported, so electric-only homeowners should look elsewhere. Overall, this pick suits tech-savvy users with multi-system setups seeking seamless remote control and energy efficiency, though those with simpler systems or electric baseboard heat might find it less suitable.

    Pros:
    • Supports multiple smart home platforms including Alexa, Google, and Apple
    • Includes wireless sensors for targeted comfort control
    • ENERGY STAR certified for energy savings
    • Remote access via mobile app
    Cons:
    • Requires C-wire or use of included adapter, complicating installation
    • Doesn’t support electric baseboard heating

    Best for: Homeowners with multiple HVAC zones and existing smart home integrations who want detailed control and energy savings.

    Not ideal for: Renters or those with electric baseboard heating, as it doesn’t support electric resistance heat.

    • Display:5-inch touchscreen
    • Connectivity:Wi-Fi 2.4/5 GHz, 802.11ax/ac/a/b/g/n
    • Compatibility:Up to 3 heat/2 cool heat pump, 2 heat/2 cool conventional systems, hot water heat, forced air
    • Sensor Range:Up to 200 ft
    • C-wire:Required (included adapter if needed)
    Our verdict
    “This is an excellent choice for tech-savvy homeowners with complex HVAC setups seeking precise, remote-controlled comfort and energy efficiency.”
  12. Programmable Thermostat for House, 5-1-1 Day Digital Energy-Saving Thermostat, Multi-Stage, 2 Heat/2 Cool, Blue Backlight

    Programmable Thermostat for House, 5-1-1 Day Digital Energy-Saving Thermostat, Multi-Stage, 2 Heat/2 Cool, Blue Backlight

    Best Value for Wide Compatibility and User-Friendly Controls

    View on Amazon

    Compared with the Honeywell X8S, the Programmable Thermostat for House emphasizes broad system compatibility and straightforward installation, making it a practical choice for many homeowners. Its large backlit LCD ensures easy readability, and support for both 24VAC and AAA batteries offers flexible power options. However, it’s not compatible with heat pump systems that have auxiliary or emergency heat, unlike the ecobee Smart Thermostat Premium, which supports more advanced configurations. Its lack of Wi-Fi limits remote access, but its simple programming features and quick setup are ideal for those who prefer manual control or don’t need advanced smart features. This thermostat is best suited for users seeking a reliable, easy-to-install device that offers good system compatibility without the complexity of advanced smart features.

    Pros:
    • Compatible with a wide variety of HVAC systems
    • Simple installation within 30 minutes
    • Large, clear backlit LCD display
    • Supports energy-saving programming
    Cons:
    • No Wi-Fi connectivity for remote control
    • Not compatible with heat pump systems with auxiliary or emergency heat
    • Line voltage systems not supported

    Best for: Homeowners with traditional HVAC systems seeking an affordable, easy-to-install programmable thermostat without requiring remote Wi-Fi control.

    Not ideal for: Tech enthusiasts wanting remote access or those with heat pumps involving auxiliary heat, as it lacks Wi-Fi and auxiliary support.

    • Compatibility:Single-stage or multi-stage systems, forced air, electric furnace, hot water steam, heat pump w/o auxiliary
    • Display:Backlit LCD
    • Power Supply:24VAC or 2 AAA batteries
    • Features:Adjustable temperature differential, calibration support, °C/°F conversion
    • Not Compatible:Heat pump with auxiliary, dual fuel, electric baseboard, line voltage, radiant-ceiling, mini split
    Our verdict

Factors to Consider When Choosing Smart Thermostat With Remote Sensors

Choosing the right smart thermostat with remote sensors involves understanding several important factors. Beyond basic features, consider how well the sensors improve temperature distribution, the ecosystem compatibility, and the ease of installation. The right model should also fit your budget while offering reliable performance and smart home integration. Being aware of potential pitfalls, like overpaying for unnecessary features or poor sensor accuracy, can help you make a smarter investment.

Sensor Placement and Accuracy

Remote sensors are only as good as their placement and accuracy. Placing sensors in high-traffic or sun-exposed areas ensures the thermostat can better gauge real living conditions. Avoid overly close or obstructed positions that can skew readings. Accurate sensors improve comfort and energy savings, but poor placement leads to inconsistent results, making it essential to consider the sensor’s flexibility and mounting options when choosing a model.

Compatibility with Smart Home Ecosystems

Many smart thermostats work best when they seamlessly integrate into your existing smart home setup, whether that’s Alexa, Google Assistant, or Siri. Check each model’s compatibility before buying to avoid frustration. Some thermostats, like ecobee, include built-in voice assistant support, while others require additional hubs or integrations. Compatibility ensures you can control your system easily through your preferred voice commands or automation routines.

Ease of Installation and Setup

While many smart thermostats tout DIY installation, some are more straightforward than others. Consider models with clear instructions, good app design, and minimal wiring requirements if you’re not comfortable with electrical work. Proper installation impacts sensor placement, Wi-Fi stability, and overall performance. Investing in a model known for user-friendly setup can save time and prevent frustration, especially if you plan to install multiple sensors in different rooms.

Cost and Long-Term Savings

Smart thermostats with remote sensors range widely in price, reflecting features like air quality monitoring, advanced automation, or premium build quality. While higher-end models cost more upfront, they often deliver greater energy savings and smarter control, offsetting the initial expense. Be wary of models that seem cheap but lack reliable sensors or fail to integrate well with your smart home setup. Consider the total cost of ownership, including potential energy savings over time.

Additional Features and Futureproofing

Beyond sensors, look for features that add convenience or value, such as learning algorithms, scheduling, or integration with other smart devices. Futureproofing your investment means choosing a model that supports updates, multiple sensors, and compatibility with new smart home standards. However, avoid paying a premium for features you don’t need, balancing future-ready capabilities with current needs to maximize your investment.

Frequently Asked Questions

Can remote sensors improve comfort in multi-room homes?

Absolutely. Remote sensors help distribute temperature readings more evenly across different rooms, preventing hot or cold spots. By placing sensors in key areas, the thermostat can adjust heating or cooling more precisely, leading to a more consistent comfort level throughout your home. This is especially beneficial in multi-story or larger homes where a single sensor might not accurately reflect the overall temperature.

Are smart thermostats with remote sensors compatible with all smart home platforms?

Compatibility varies between models. Many popular options support major voice assistants like Alexa, Google Assistant, and Siri, but some require additional hubs or integrations. It’s important to verify each thermostat’s ecosystem support before purchasing, especially if you already have a smart home setup. A compatible device ensures seamless control and automation, enhancing your overall smart home experience.

Do remote sensors require regular maintenance or replacement?

Remote sensors generally require minimal maintenance, mainly ensuring they stay clean and properly positioned. Battery-powered sensors may need occasional replacement or charging, depending on the model. It’s wise to check the manufacturer’s recommendations for sensor upkeep to maintain accurate readings and reliable operation over time. Proper placement and maintenance help sustain the benefits of remote sensing for energy efficiency and comfort.

Is it worth paying extra for a thermostat with air quality monitoring?

For many, yes. Air quality monitoring adds value by providing insights into indoor conditions and helping improve overall health and comfort. Premium models often include features like humidity sensing and air purifier controls. However, if your focus is solely on temperature control and energy savings, a basic model might suffice. Consider your specific needs and whether extra features justify the higher price point.

Can I install multiple remote sensors myself?

Many smart thermostats allow for easy installation of multiple sensors, often through simple pairing via the app. However, placement is critical—sensors should be in areas where their readings will be most representative of your living space. If you’re comfortable with basic DIY tasks, installing multiple sensors is usually straightforward, but consulting installation guides or videos can help ensure optimal placement and performance.

Conclusion

For most homeowners, the ecobee Smart Thermostat Premium offers the best overall experience, thanks to its reliable sensors, air quality features, and robust smart home compatibility. Budget-conscious buyers will find the Sensi Smart Thermostat to be a dependable and affordable choice, while those seeking premium features with future-proofing should consider the ecobee Total Security and Savings Bundle. Beginners or those installing in a small home may prefer models like the Honeywell T9 for its ease of use and straightforward setup. Ultimately, your choice depends on your specific needs, home size, and smart home ecosystem, but this list provides a solid foundation for making an informed decision.
