As a life-long WDW person (been there more 20 times) whose first trip to DL was a week ago, all I can say is
Rides in common and which is better:
Disneyland Railroad: Disneyland
AstroOrbitor: WDW (just because of where it is)
Autopia/Indy Speedway: Disneyland
Buzz Lightyear: Disneyland
HIStA: Equal
Space Mountain: Disneyland
Star Tours: Equal
Dumbo: Equal
Small World: Disneyland
Carousel: Equal
Tea Party: WDW (covered so not closed in rain)
Peter Pan: WDW
Snow White: about the same
Big Thunder: WDW
Tikis: Disneyland
Jungle Cruise: WDW (indoor temple is better)
Haunted Mansion: WDW
Pirates: Disneyland
Splash: WDW (the Disneyland logs are torture devices)
Winnie the Pooh: Disneyland
Soarin': Equal but better themeing at CA
Toy Story: Equal
Tower of Terror: WDW
Muppet Vision: Equal
Tough to be a Bug: Equal, but the queue is way better at WDW
All just my opinions of course.
