DHS and it isn't even up for debate. Anyone saying USF over DHS must either work for Universal or have never been to DHS.
DHS, while light on attractions is filled with top notch attractions from iconic characters.
USF is filled with mediocre attractions to horrible attractions, many of which replaced great attractions and alot of them are from flash in the pan characters.
*Shrek is a terrible ride, show, and character and should have never replaced the WAY better Funtastic World of Hanna-Barbera.
*Twister is boring and based off an even more boring film.
*The Simpsons is OK but grows stale after the first ride and replaced the much much better Back to the Future Ride.
*MIB, again cheap ride based off average movies.
I do love ET, Jaws, Terminator ...and I think the Mummy is ok but nothing at USF comes even close to touching the perfection of themeing, ride, story, etc of Tower of Terror ... or even RNRC, TSM, ST, or even VoTLM.
