A few ride highlights:
Make sure to check out Pirates of the Caribbean and Space Mountain as they are pretty different than the WDW versions. You might though notice that The Matterhorn is quite similar to Space Mountain at WDW.
Many rides have small differences and are still worth checking out, like Haunted Mansion or It's a Small World. Rides that are identical are Toy Story Mania, Little Mermaid, and all Star Wars rides.
There are many unique rides that you should check out, like the Fantasyland Dark Rides, Indiana Jones (though you might recognize the technology for it), Radiator Springs Racers (also similar to a WDW ride in some ways), and the Incredicoaster. Also, Guardians of the Galaxy is a rethemed Tower of Terror but it totally worth doing.
