Epcot is actually probably the favored child of the WDW parks. In DL, Disneyland Park is definitely the favored child. In WDW, it's Epcot, in spite of Epcot having similar issues to Disneyland (hint, the entirety of Disneyland's Tomorrowland

). It was definitely the cleanest out of all the parks last trip. Entertainment is also the best over there out of any US Disney park, as is the food (DL people are probably gonna try to come fight me but it's true). Oh, and GOTG is absolutely the best modern ride in the American parks. Soarin' looks much better since they updated the film, and now TT is getting an update. Definitely still needs some updates but yeah, definitely the favorite child of the parks. DHS suffers the same mismash effect as DCA (but honestly, I kind of like DHS better because Sunset Boulevard is still there and they just did a fantastic job there in the 80s/90s, and Avengers Campus was kind of disappointing) and AK still needs work, though I'm super excited for Indy.
I used to be an MK person and now am in camp Epcot. MK now I just go into and am disappointed because it's not Disneyland. I'm hoping the upcoming changes will revitalize it. I'd just rather be in the other parks nowadays after I'm done with Space Mountain, PeopleMover, and Haunted Mansion (I still like our Mansion much better than the DL version). And maybe Country Bears because I actually kind of like the new one better (I know, blasphemy). MK is their cash cow and it shows; they just don't care as much as they do about DL.
