I have a lot of favorites, but story-wise Tower of Terror is simply the BEST! The whole attraction is Imagineering at it's finest, and it starts the moment you approach the building. Just walking up that slight incilne into those old gates, you really feel as if you are leaving the world behind and entering the story. That's what Imagineering is all about, after all. I feel as if the ride is even not as enjoyable if there is too short a line, if it's your first time, that is. (If you're doing the ride ten times in row on an empty day, however, it does get annoying!) But I must say that E:E also accomplishes this rather well. I also think that the ride is not as immersive of an experience if you go through fatspass or single rider.
