From what I see people around here prefer the Carrier Infinity over the Trane ComfortLink thermostats.

Infinity
--better handling humidity

Trane
--better Electronic defrost demand

It also looks like you need to go with the full top of the line Trane equipment in order to get the full communications between all the pieces, but on the Infinity thermostat it works with some of the mid-range equipment.

Am I correct ? Any other differences ?
