Have you been to both? Because if you haven't you really shouldn't be commenting in this thread.
Anyway, I've been to both events, several times. I would say that each venue has their "on and off" years. But even the best years as USH is very, very, very hard to beat Orlando. In, fact, it's simply just an unfair comparison.
The park at USH just doesn't have the same kind of room that Orlando does, and you have to also remember, that aside from the theme park, it IS also a working movie studio, and that plays a huge impact on what they can do.
USH puts on a TOP NOTCH event, and it's easily in the top three in the world for Halloween events.
Having said that though, Orlando is just on a different scale, and the event blows away anything else I've ever seen as far as theme park based Halloween events go.
Every year they have completely original mazes, the "vibe" at the show in Orlando is a lot more crazy and fun (it's probably the alcohol helping that), and there is just more of a "legacy" about the show in Orlando, much like there is for Haunt at Knott's.
At the Bill & Ted show in Orlando, people really GET INTO IT, because it's been a legacy show there for 20 years. In Hollywood, people watch the Bill & Ted show, they seem to like it, but you just don't get the same audience reaction, nor do they really seem to understand "why is the park doing a show based on characters from an 80s movie???" It makes sense in Orlando, and it's fun in Hollywood, but the guests don't seem to 'get it' as much.
I'd go to both events and form your own opinions. HHN is great on both coasts.

Well I'm glad to hear the one in Orlando is good. Ill definitely try to go this year, unfortunately a trip to Hollywood is out of the question right now (college budget and all).
