Ecobee with modulation and variable speed furnace?

I have a Trane XC95m furnace (modulating gas valve, variable speed blower) and XL1050 thermostat. The thermostat does not work as advertised (and Trane agrees) and I am thinking to switch to the Ecobee 4. Trane says the furnace can be wired to work with a 24V thermostat. Can the Ecobee control all the functions of that furnace, and if not, what will I be giving up??? Would there be a better choice?

    The furnace will run 40% with W1 call. When W2 is called the furnace will increase the demand in 3% steps until either W2 is satisfied or running at 100%. I don't think you will lose much of anything furnace wise.
