Sorry no one has responded to this post yet. I have thought about your question and while both class of ships receive high marks for their accessibility and facilities, I think I would lean toward the Voyager class for one reason. There are a limited number of elevators on the Radiance class. For some reason there is not a bank of elevators situated on the aft of the ship. This makes getting to the venues on the aft end of the ship sometimes a very long trek.
