I think I'm the only person that actually prefers the SD version...
I think the coaster part is better at SD. And it LOOKS better to me too. The only thing I dislike (actually HATE!) is the lift which takes you to the second level to start the coaster... it's very cheap feeling (and looking) inside with materials just draped in front and either side of the lift. Some NICE effects and sturdier framework could make it a lot better.
DEFINITELY try and ride it early (if you're there at opening or just after) and then just before you go home though. Preferably a couple/few times each time. The queue can get crazy during peek times.
Also, unless it sweltering, I'd give Shipwreck Rapids a miss. You get quite literally, DRENCHED!!!!!!! I'm all down with getting wet (even soaked) on rides but not literally soggy to the bone. You go under a waterfall that doesn't stop!!

It was fun trying to dry off by the fire grill out front of the Shipwreck Reef Cafe.
Have a great time though!!
