I'm a bit surprised at my own reaction here, but I'm going to say Hollywood.
I think Florida functions better as a park. It has more distinctive sections and a nice flow from land to land. This is as compared to the very irritating Upper/Lower lot that takes up large chunks of time just to get between rides. Then, there's Florida's superior ride collection: the better Mummy, the better Potter (land and ride), solid dark rides in ET Adventure and Men in Black and even a major coaster in Hollywood Rip Ride Rockit. Hollywood does have the amazing Jurassic World ride, but it's not quite enough to tip the scales.
So, why do I prefer Hollywood? It's the actual Universal Studios. Not a recreation of it but the actual live and functioning place that people work and film in every day. As a film buff, I get very excited by this: getting to see familiar and famous sets from tons of Universal films. That's not even considering all the famous show scenes on the tour (experiences that are now mostly extinct in Florida). So, ultimately, I think it's the tour that makes Hollywood feel more unique or worthwhile in my own book. It hurts that I've spent more time in Florida throughout the years: being able to see its ups and downs. I can imagine that Super Nintendo Land will really help Hollywood feel like a fully realized park, as it is a bit of a half-day park in its current form.
