It's funny you say that, because even as a Hollywood local, I always thought Orlando was better. But I've found many (though certainly not all) in Orlando like Hollywood better.
Arguments for Hollywood include that Orlando's backwards section is a joke, there's very little continuity (meaning there's long passages where seemingly not much happens--mainly the "backwards" park and the long turn around really kill the momentum), and their fast section is a bit rough, jarring, and uneven in speed.
While arguably Hollywood is much less thrilling, in it's favor: much more significant backwards section, the pacing is better (the dark ride sections building pretty nicely to the fast section, and the fast ride really holds it's momentum), and it's pretty smooth. Ending still sucks though, can't argue that, lol.
