Should I buy the Ecobee Smart Thermostat Premium or Nest Learning Thermostat?

Buy the Ecobee Smart Thermostat Premium if you care most about multi-room comfort, room sensors, and air-quality awareness. Buy the Nest Learning Thermostat if you want the most hands-off experience and like the idea of the thermostat learning your schedule automatically.

My pick for most homes: Ecobee Smart Thermostat Premium, especially if your home has hot/cold rooms or you want more control over comfort by room. Nest is still the cleaner choice if you want to set it up and mostly stop thinking about schedules.

Before buying either one, verify HVAC compatibility, whether your system needs a C-wire or power adapter, and which smart-home ecosystem you prefer.
