I use QSI, I like it, but you should focus on the controller system first, i.e. the power supply, booster, command station and the cabs. That is the decision that is not easily undone.
You will have lots to time to try different decoders in your locos, and you can use any decoder with any DCC control system (except some cheaper, entry level stuff).
