I would also have to say Animal Kingdom, but not because of the lack of rides. I just am not all that into animals and nature. Believe me, there are people out there who love this stuff, and rate AK as their fav. park, and that is great. Although the AK can be compared to a zoo, it is the best dang zoo I've ever been to. i think that AK is put down too much sometimes.
In my opinion, E-ticket rides do not mean a great park. Everyone seems to think that the parks are all just ways to put big, popular, themed rides in them. I think that that is best kept for the Magic Kingdom, because that is the only park that I think was ever meant to just be a place to go on a bunch of rides. Epcot was not made for "themed rides about the future and different countries in the world", it was made to showcase future concepts and different cultures in the world, and it does a fine job of doing that. The Studios have always tried to give the image of a full working motion picture studio. Although they are currently lacking in the live action movie productions, the animation studio is doing great, and here we can learn how it is all done. The Studios have always seemed to be the best place for shows, whether it be on stages or spontaneously beginning on Hollywood Boulevard. As for animal kingdom, it showcases, well, animals, and does so with plenty of walking trails. It is popular among adults who I know enjoy seeing all the different creatures and learning about them. I guess I am just not into that, but thats ok.
So with all of these different "meanings" behind the parks, I don't think that sticking big thrill rides in the middle of them is the only way to enhance their quality. Don't get me wrong, I love the big rides, and they also make the parks great, but I just hope everyone knows there is more to Disney than just the rides.
Sorry, I spoke too long.
Oh well. have a nice day!
