I know people that got bored at the main park, however, LOVES Islands. And I agree to a certain degree, the quaility of stuff in Universal is a notch down to Disney (for instance, Universal does have ty audio-animatronics).
But if I had to choose, I prefer going to Universal. I love the history of the park, and the history of the company.
Also like to point out that you missed out on Islands completely. There's PLENTY to do there...
Nothing at Disney holds a candle to the Spiderman ride. That ride itself is worth the ticket.
To the animatronics comment, I disagree - while in general Disney has better AAs, Universal's AAs are nothing to sneeze at (Mummy, ET, Jurassic Park, Cat in the Hat, Men in Black). Plus, Universal can keep most of their AAs reliable (Hopping Brer Rabbit, Yeti)...
Agreed, Universal just has a certain richness to it. I still LOVE going to Disney, though.
And with Spiderman, agreed 100%. To any first time rider the ride is jaw-dropping - and even after riding it over 25 times I still love it. Nothing at Disney comes close.
Here are a few particular superior Universal attractions to those who say Disney is always superior -
Men in Black >>> Buzz Lightyear
Terminator 2:3D >> Any Disney 3D show
The Simpsons Ride > Star Tours
Revenge of the Mummy > Expedition Everest
Disaster > Backlot Tour
Popeye >>> Kali River Rapids
Cat in the Hat > Pretty much any standard Disney dark ride
One Fish Two Fish > Dumbo (One Fish Two Fish is just more fun and feels worthwhile)
Spiderman >> Any Disney Ride
