Great post question!
We have stayed in a handful of deluxe resorts, here's how I would rate them:
THE BEST
#1 Favorite - Wilderness Lodge - the section where you can rest on the ledge near the waterfall is my zen place!
#2 Favorite - Kidani Villas - Love this pool and the kids slide - also really enjoyed the splash zone near the pool, it was like a cute oasis
#3 Favorite - Bay Lake - could be bigger, but we always enjoyed our time there (although due to smaller size, gets crowded easily)
#4 Favorite - Grand Floridian - on our trip we stayed at the quiet pool right near Boca Chica and loved it
Honorable Mention
Poly - But because it is too small of a pool for the number of people at the resort, the overcrowded conditions take it out of the running for us. But when its not crowded, just love it!
Could never understand why they didn't make that pool bigger when they added the villas.
Not So Much
Beach Club - Wasn't a great fan of stormalong bay, my kids were younger at the time and enjoyed the sand bar, but was so shallow I felt I truly couldn't "swim" in the pool, also just don't love the set up with the bridges etc.
Boardwalk - Clowns creep us out - need I say more?
