Batman: the Ride and Superman: Ultimate Flight are both here at Six Flags Great Adventure in New Jersey so, since they're clones, I can help you with those.
Batman is fun, but definitely not my favorite. It's very fast, but very compact, so it likes to whip you around a bit. I suggest not sitting in the front because, on the loops, you're facing the ground when the train slows and loses G forces, so you kind of feel like you're falling. But you might like that sorta thing :shrug: Overall, I would ride it, but not if the line is more than half an hour (but that's a personal statement).
Superman is a very, very fun coaster. Lying on your stomach - at first - is a little unsettling, but once you start moving you get used to it instantly. I like sitting in the front because you see more and, in the back, you get a lot more G's on the pretzel loop and it really pushes in on you. However, the line moves painfully slow due to the multi-step boarding. Overall, great little coaster, but get there just as the park opens or you'll be waiting for at least an hour.
Just my two cents :smiley:
P.S. Just something you should know about Six Flags (at least in New Jersey): when they say it's an hour wait for a line, it's anywhere from 18 to 30 minutes. We time it every time - from back of the line, to loading - so this is pretty accurate. But then again, there's the occasional slow-mover like Superman that will take the full hour.
