I don't consider myself an expert, but based on reading about control systems here, one major consideration with DCS is the way in which the track is recommended to be wired [see DCS Companion], known as star wiring, which may or may not add some further complications to powering your layout (depending on it's size and complexity).
TMCC/ Legacy, Lion Chief, and Conventional control wiring methods are more forgiving of how power is distributed.
