For any attraction you mention, there will be a handful of people who say it is their favorite.
I'd also vote Twister and Earthquake because the pre-show is so long and they're not really rides. I usually walk right by them on the way to The Mummy and MIB.
Earthquake seems to be the next attraction to go, or have a make over. The movie came out before most kids were born. Some say the movie part doesn't matter to understand the ride. Sure, I get it, but Universal updates older attractions when the movie is stale, and Earthquake would definitely be the oldest at 1974. 33 years, and they really didn't have any 30 year celebration in 2004, at least I don't remember any.
