Nitro was amazing. I think that it was better than Millennium Force. Even though they both have good airtime, Nitro had more and if you are less than around 5'7" (around there I think) your feet don't touch the bottom of the trains and when you go over a hill your feet fly up and its awesome. The hills seem steeper than any other coaster that I've been on, and the drop and the hills felt a lot steeper than on MF. The coaster is extremely smooth too and everythings so comfortable when riding it. Its one of the best coasters I've been on but I think that Medusa is slightly better, but they are very close. I really can't describe how great Nitro is, you gotta ride it to know how amazing it is.
