Unless you are real scared of heights, none of them are very scary but fun to try at least once.
The one that hangs over the building is ok if you are in the front seat, otherwise boring.
The cherry picker one is cool to be able to look straight down with 1000 or so feet to the ground, kinda like you were parachuting and it doesn't spin fast enough to make you dizzy.
The roller coaster isn't bad for such a small one, fairly jerky and it goes around three or four times to give you a longer ride, nowhere near as good as NYNY though, the main thrill is knowing you are up that high.
The best IMO is the big shot, just to feel those G's and the one second of weightlessness at the top where if you are short enough your butt will float a foot off the seat.
The funny thing about the big shot is if you go on it a second time. Like right after or even a few months later, your brain will remember the feeling and be prepared for it so it will seem lame and you will wonder if they made it slower or something. But if you give it a year or more and try again it will be just like the first time. (Sounds like sex

)
I have yet to try the rides at night, that should be better as things seem higher at night and you'll get a good view of the city lights.
