Ooh this is a tough one for me.
A lot of theme park nerds crap on Transformers, but I actually love it. It's more chaotic and has more aggressive, simulated movement than Spider-Man and the sound and visual design is top notch (as it also is on Spider-Man). Where it falls short of Spider-Man is that it lacks the solid pacing that Spider-Man has and is instead chaotic the entire time, but that does make it more thrilling and more accurate to a Michael Bay movie.
Dinosaur, when everything is working right, might actually be Orlando's scariest attraction. The visuals get a little sparse, but the darkness does add to the thrill level. The story is also about as creative as it gets for a theme park attraction.
I suppose I would give the edge to Dinosaur, based on it being a unique experience in Orlando, whereas Transformers does have the superior Spider-Man right next door. That said, Dinosaur has been in very poor shape lately, sadly.
