Went with Hulk.
While I love the queue of RnR and the music, (as well as the preshow), the coaster itself is over after the initial launch. The cardboard cutout theme with blacklights just doesn't cut it (and that's saying a lot compared to the extreme minimal theming on Hulk).
The launch tunnel of Hulk is awesome and that coaster doesn't really let up until the very back portion.
Watching from below, you hear the roar of the Hulk from the coaster wheels. Visually, it's an appealing coaster to see across the lagoon.
So sure, it has dropped to my #3 coaster in Islands of Adventure (from an initial top spot), it is still IMO, far better than Rock n Rollercoaster.
