Up ahead, there's a signpost. It reads California Adventure. But before you check into this hotel, you should think twice. You are about to enter... The budget cut zone.(Music concludes, dramatically of course)
Seriously. This isn't even a contest. I'll never forget going on the ToT at CA, and discovering that the elevator doors in basement boarding area didn't open to an elevator, but rather a hallway which leads to the elevator. The only good thing that the CA version adds is the mirror illusion just before the drop sequence (which, I must admit, is pretty cool). Other than that, the WDW ToT wins hands down. The DL's version's lack of a forth dimension room where the elevator leaves the shaft places it at an unrecoverable disadvantage.
Without question the Florida ride is superior, but part there is a part of the California ride that is better and that is the audio. The audio in both the library and ride are superior at California Adventure.
