Their shopping district and park identities are stronger, though I was still amazed how little shopping there was when I was there in April. My friend and I popped over for a layover (our original plan was to visit AK at WDW for 4 hours, but Disney reservations killed that plan). We walked around and all of the fun shops from Hollywood's City Walk that I remembered just weren't in Florida. It was 99% food. So we visited the legacy store and went to Toothsome (great food, kind of mediocre decor with flat screens being 90%).
For the parks themselves, USO Resort does beat Disney a few times. Mummy is great and much better than Rockin Roller Coaster or Space Mountain. Popeye is my favourite rafting ride whereas GRR is inoffensive but bland. MIB is miles better than Buzz Lightyear and a hair stronger than Midway Mania. Diagon Alley is the best theme park experience I've had, and I'm not even a huge Harry Potter person.
That being said, the rest does decline quickly in terms of quality. Spiderman is great in ride design, but I do feel the cost-saving in the queue and production design. Kong was a great queue and total misfire of a ride. River Adventure is fun, but I preferred the Hollywood version with the car gag. ET was great when it debuted, but it needs to be updated as it doesn't compare to Fantasyland rides in terms of quality. Cat in the Hat was a mess when we rode it last.
I do love the USO resort, but I have found that I need a park hopper to be worth it. Neither park scratch the itch of a complete theme park experience. But I think that's an Orlando issue as I find that with Disney's offerings too. There's just so fewer attractions and variety per park out in Orlando vs So Cal.
Disney just needs to go crazy with DTD. Make it weird and unique, not generic outdoor Southern California mall.
