It's all opinion, but Jurassic Park River Adventure is the king of dinosaur themed rides. The T-Rex at the end with the drop is so climatic, it's just perfect. DINOSAUR is just too dark, too loud, a lot of things are broken and not working, and it's a confusing and frightening experience.
Jurassic Park River Adventure is a more intimate and engaging experience that builds up to a climatic and dramatic ending. Plus, the T-Rex at the end is leagues better than that large dinosaur head that charges at you and blasts nasty smelling air in your face.
I still enjoy DINOSAUR, just not as much as Jurassic Park. Plus, nothing beats hearing the theme song and having those Jurassic Park gates open. It gives me chills!
But yes, most of the AAs in Jurassic Park River Adventure need some major refurbishment.
