I enjoy all these parks from top to bottom. This list is not about which park has the best vision or execution, but which I would like to visit today...
Disneyland - the best attraction list and still has classic vibes around the park and dark rides, solid food, etc
Epcot - was number 1 for me in the 80s/early 90s and is a shell that of that magic place they somehow built. However, there are still remnants here, and world showcase is unique experience with much to offer eating and drinking wise. Plenty to do overall.
MK - will hopefully be number 2 again after the updates - but too little that gets me excited as we speak (Thunder closed, Tiana downgrading Splash, etc).
HS - Again, no longer the feels of MGM - but still has some vibes, I enjoy the park entrance streets/music (and now streetmasphere!) and several top attractions that cant be ignored.
DCA -It would be last w/o Radiator Springs - fine as an adjunct to Disneyland to find some solid attractions, but lacks any discernible identity on it's own.
AK - On the flip side, I love the theming and the exploration ability of this park. Unfortunately, Everest and FoP make me a bit sick (although I still ride them from time to time), so very little to draw me in attraction wise. Little to no evening experience, which I love at parks. Although the lands are beautifully re imagined with amazing detail by Joe Rhode and team, nepalese villages and east african markets just arent the places I dream of repeadilty escaping to, in comparison to what the other parks have to offer.
