While I think Dinosaur is a marvel of modern engineering, and manages to do something that no other ride on the planet can do (which is get dumber ever time you ride it!), I voted for Crystal Skull. Like most things at TDL/DisneySeas, they take previously existing Disney attractions and improve upon them. Not that the Disneyland version sucks or anything, but CS is just better.
And yeah, voting in polls like this when you haven't actually been on all the attractions is kind of lame, and doesn't give you a real result. But that's the internet for you...
