While I usually champion my own coast, the simple reality is that an "OK" house at Universal Orlando is usually on par with a "good" house at Universal Hollywood.
Universal Orlando doesn't make bad houses, and it's part of why I fly over there every year. If you've only ever been to HHN at Universal Orlando, you are spoiled and you just don't know what you have. That doesn't mean I don't enjoy Universal Hollywood, but I only wish we got Orlando's budget.
