IOA seems to always get the crowds, and many people seem to prefer it over Universal (in my experience).
I personally enjoy Universal more, and like the theme a lot better (a movie-style theme). IOA is more of a fantasy-based theme park - almost like a more adult-oriented Disney. Universal, to me, has its own unique style.
Now, with the opening of Harry Potter, IOA has higher attendance than US, and people probably go to Universal as an afterthought.
I personally think Universal is a more interesting theme park, but from what I've seen, it's less popular than IOA.
