Whenever I stay at a moderate resort, Port Orleans French Quarter is my far-and-away favorite. I love the small size, the lovely theming of the cobblestone streets and lighting, the bar and live music is great, they have great beignets, and the boat to Disney Springs gives me dozens or restaurants and bars to hit every evening. The busses are usually dedicated - and even the rare times they share with Riverside, French Quarter is the first stop coming back from the parks.
Strangely, I prefer Coronado over Riverside - even though Riverside shares the boat access to Disney Springs with French Quarter, has a decent restaurant, and Yehaa Bob is great - plus nice theming...but if I'm staying at a sprawling multi-stop resort, Coronado does have better on site selection of restaurants and bars - Three Bridges is a great relaxing spot for late drinks or food, Toledo is excellent, Destino has a few very nice bars, Maya Grill is an underrated spot for pretty decent food, Rix is a good sports bar, and the food court has some nice options.
So French Quarter #1, Coronado #2, Riverside #3.
