I've had a Nest as well I find the Honeywell Thermostat pretty superior - was installed by the contractor in my knew home - controls are intuitive and the app and interface are great, it runs 2 units and 3 zones it's been great.
I like the thermostat. Wish there were better instructions on how to program it. The leaflet that came with it was of little help. I did mine by trial and error and am still not sure I have it right.
I was disappointed that during the three days while the app was on my phone, it drained my phone battery so rapidly that I needed to find emergency charging resources while I was traveling. When I removed the app, the battery life returned to normal
