I'd say MK Epcot and MGM are all pretty close for me. I gave it to Epcot though for the food. MGM has my favorite ride, ToT, so it has to be up there, plus I love RnRC and the GMR. MK is maybe the best all around park for me in that it has so many rides, including probably my second fave ride HM, with Splash and Space and Pirates all up there too of course. Plus just the atmosphere makes you feel like a kid. EPCOT though has some great attractions, and SSE is pretty close with HM for my number 2 fave ride. EPCOT's kind of got me on mixed feelings though, because although I think TT is great and Soarin' they've replaced some of my all time faves in WoM and Kitchen Kabaret/Food Rocks, M:S I think is okay but I loved Horizons, they ruined Journey Into Imagination etc. So, it's hard for me to put them on top, but like I said the food there is the best and that put them over. That and Rio Del Tiempo, which is a ride from my childhood I will always cherish.
AK wasn't even close to those 3. The Safari's neat, Dinosaur is pretty fun, Everest is pretty awesome, but none even come close to being favorites. Additionally they have like no really nice dining places (I don't like Rain Forest Cafe at ALL), the park is so big but attraction wise it's like a 1/2 day at best, and it always feels like it's 130º and as humid as the Amazon in the summer
