Here is my comparison b/w Disneyland and WDW:
Disneyland:
FantasyLand:
Only at Disneyland:
Snow White’s Enchanted Wish
Pinocchio’s Daring Journey
Mr. Toad’s Wild Ride
Alice in Wonderland
Storybook Land Canal Boats
Casey Jr. Circus Train
Matterhorn Bobsleds
Sleeping Beauty Castle Walkthru
Storytelling Theater (Specifically the Tangled Show as the Enchanted Tales with Belle retells the Beauty and the Beast story so you could say they are similar and Enchanted Tales with Belle is better given the whole walk thru prior and audience participation)
Whatever replaces Mickey and the Magical Map maybe since that was unique to DLR
Better at Disneyland:
It’s a small world
Mad Tea Party
Tinker Bell/Fairies Meet & Greet for the themed outdoor garden
Better at WDW:
Peter Pan’s Flight
Dumbo the Flying Elephant
Wash aka the Same:
Carrousel
Princess Meet & Greets when they’re available
Only at WDW:
Seven Dwarfs Mine Train
Enchanted Tales with Belle (or in this case maybe better than the Storyteller’s Theater version but unique enough I’m putting it here)
Ariel’s Meet & Greet
Circus Stars Meet & Greet
Merida Meet & Greet too I think
Tomorrowland:
Only at Disneyland:
Finding Nemo Submarine Voyage
Better at Disneyland:
Space Mountain

Better at WDW:
Astro Orbitor
Only at WDW:

Nighttime shows/parades are different too so worthy of seeing both but probably comparable for the most part. I’m probably forgetting things…but that’s just what i could remember. I think there are enough differences they are both worthwhile experiences. I prefer DLR overall but parks like Epcot and Animal Kingdom make WDW a very worthwhile trip for me as well.
