Programmable Thermostat Consumer Reports Programmable Thermostat-- Should I Purchase One Built By The Same Company That My A/c Is?

Programmable thermostat-- should i purchase one built by the same company that my a/c is? - programmable thermostat consumer reports

I am willing to put money with a programmable thermostat. I installed an old boiler (radiator heat) and a brand new Trane air conditioning, in January this year. Is there an advantage for the purchase of a Trane programmable thermostat thermostat to a different brand (my A / C Trane is)? Disadvantages?

Thank you.
