Disneyland has Indiana Jones Adventure, Roger Rabbit's Car Toon Spin, Matterhorn Bobsleds, Mr. Toad's Wild Ride, Finding Nemo Submarine Voyage, and the better Space Mountain.
Just a few noticable things that Disneyland has that Magic Kingdom (Or all of WDW) doesn't... Other than some attractions, Disneyland is also a lot smaller (A lot less feat drag, eh?).
Magic Kingdom has some classic attractions that once lived in Disneyland... Attractions like the Country Bears, Carousel of Progress, and the Peoplemover.
