Lot's of operation problems with the Nest 3 without the common wire. We have had customers that Nest told to have common wire installed to fix problems. We prefer to install Ecobee because they come with the adapter to add common to 4 wire system.
Nest has sensors you can now buy to monitor temperatures in other rooms. You can also adjust the schedule to use different sensors at different times. Also missing here is mention of Nests sun shade feature, where it adjusts to compensate for being in sunlight and getting an inaccurate temperature reading.
I'm shocked you consider Nest working without a C wire to be an advantage. There have been a lot of reported problems of the Nest's "power stealing" functions.
Also, design getting 10 points when they are so similar? That's just a personal preference thing.
Finally, any review of smart thermostats should mention that they are fairly pointless if you are smart enough to program a thermostat. The only savings would come from delaying a temperature change if you're not home, and for most people that would be an extremely nominal savings over even a 10 year period.
I'm surprised you consider the Nest not requiring a C wire to be an advantage. There are lots of reported problems with Nest's "power stealing" feature.
Also, the design should not be worth any points--they are very similar and it would just be personal preference. That's a tie.
Finally, and review of smart thermostats should mention that they are unnecessary if you are yourself smart and able to program a thermostat. The only energy savings from a smart thermostat would come from being able to delay a temperature change if you're not at home, and for most users that savings would be nominal even over a 10 year period.
