I'm pretty sure all of the values are outside entry. I've stayed at All-Star Movies and Pop Century. Both were comfortable rooms with decent food courts, cool theming, and good value for the price. The pools were just okay, no slides or hot tubs, etc. You'll have to stay at a moderate for a better pool. For better amenities in general, you really do want to look at a moderate like Caribbean Beach, Coronado Springs, etc.
I suppose the Skyliner access at Pop and AoA could be nice, the bus lines can be dismal.
The general consensus is that All-Star Sports is frequently the cheapest and is more likely to be filled with youth teams (roving bands of 15 year old hooligans). But I've seen teams at other values and some moderates as well.
EDIT - Forgot to answer the most important question. Favorite. I really do like All-Star Movies. The Fantasia wings surrounding the main pool are so pretty. The food court is really tolerable, especially for breakfast. The movie theme really appeals to me. If you don't plan to spend a bunch of time in your room, it's great bang for the buck.
