USH has Transformers, Mummy, Jurassic World, Mario Kart, Studio Tour, Hogsmeade, Water World, Minons and soon F&F coaster. Sure that can found at other Florida parks. However, USH IS a working studio in Burbank/Hollywood. USO is just a theme park about movies that pales in comparison to IOA next door. It's the low rent park of the Orlando Universal properties. Who would want to go to it after Epic Universe opens.
Doesn't USO also have Minions?
For me:
Diagon Alley > Hogsmede
Rip, Ride, Rocket = F & F coaster. Unthemed coasters in a theme park.
Bourne Stunt Spectacular = Waterworld. Waterworld has better scale but is getting old.
Mummy USO > Mummy USH without question
Transformers USO > Transformers USH. Same ride, but better show building
ET Adventure < Secret Life of Pets. ET is a better ride system, but it needs a refresh.
Springfield USO < Springfield USH. Almost the same from what I recall, but extra spinner
Yes, USO does suffer from Florida Park Syndrome where attractions that can fill a theme park in California are spread amongst 2-3 parks in Florida. IOA stole Jurassic Park from USO, but it also enabled MIB to occur, which is my favorite shooter attraction to date. Diagon Alley is peak theme park for me. Mummy in Orlando is my favourite themed coaster.
IOA also suffers from a mix of quality and too few attractions. Kong has a great facade and queue but is incredibly disappointing. Suess Landing has so little to see or do. Superhero Island has Spider-Man, which is an older fun ride with a cheap feeling queue. Velocicoaster is a great coaster, but I wish they hadn't cut the show scene. Toon Lagoon is irrelevant despite having the best rafting ride I've ever experienced. Ripsaw Falls looks fantastic outside, but the ride is very cheap feeling. Whenever I visit IOA, I typically just do Jurassic Park/World stuff, Harry Potter stuff, then hop over to USO for the better rides (Mummy, MIB, Gringotts.) Collectively, they end up being a full day park.
