I answered buses, although last time and next time we took/take the car.
I wouldn't rent a car for a WDW stay, because I had almost only good experience with the buses, but if we come from someplace else and already have a car, it's nice because it's so much easier to go from one resprt to the other.
I usually plan our ADRs accordingly: if we have a car, we eat more at resort restaurants, if not we tend to eat in the parks, DTD or at our own hotel.
