I don't necessarily think this movie was better or worse than Ang Lee's version--because the two are almost completely different animals. I actually liked Lee's 'Hulk'; Louis Letterier's 'The Incredible Hulk' is just bigger, louder, and thinner on the character development. (Oh, and the CGI in this one is amazing.) Both films are pretty good in their own ways, methinks.
Much better than the first Hulk movie (with Eric Bana); this re-do is at least headed in the right direction. But it falls short... a little too contrived and action-heavy (although with a Hulk movie, the action's obviously going to be heavy). Just not that good
