People only like WWoHP because it's new. Of course everybody's gonna want to buy butterbeer because they've never had it before and want to know what it's like.
While I've never been to Universal-Orlando, I checked out some YouTube videos of their rides last night, and I've got to say...while the rides may be fun, they don't have any of the magical-ness (not actually a word) that the WDW rides have. You can see ALL of the service entrances, all the infrastructure, and from the top of most of the rides, you can even see a lot of the warehouse styled buildingings that house other rides.
I'm still gonna go to Universal when I get a chance just to see what it's like, but nobody does it like Disney (even if it's not up to the standards it once was), so people should just stop complaining and enjoy both parks.
