Top Thrill Dragster is at Cedar Point. Kingda Ka is the one at Six Flags Great Adventure in New Jersey. Millennium Force is one you don't want to miss. Power Tower is a good flat and if it is working, so is Chaos. Wicked Twister is awesome and looks great on the beach. Disaster Transport is a must miss unless you want the coaster credit. Magnum XL200 is pretty good with lots of ejector air time. The Mantis is a good standing coaster. Unfortunately, it has slow loading/unloading, so the line is ususally long. Raptor is still ranked in the top ten inverted coasters in the world and is a real thrill. Mean Streak is a decent wood coaster and has some good head choppers. Geminii is a cool racin coaster with some good air and a great final helix. Blue Streak is pretty decent and has some air time. I would also give maXair a try, even if you have been on Delirium at PKI. From what I have heard, maXair gives two more full swings than Delirium. Cedar Creek Mine ride is ok for that kind of coaster...no better and no worse than Adventure Express. Dragster is a very short ride, but the rush is amazing.
