Can anyone rate the scariness of the coasters at Universal Orlando?

Well, I'm probably going to Universal on Saturday. I've been once before, and the only coasters that I rode were the mummy and that little woodpecker ride thingy. So, can anyone who has rode them make a list of all the coasters in both parks, universal studios and islands of adventure, in order so i know which ones are the scariest? Also I have ridden other coasters in different parks before, but I've never gone on one that goes upside down, and I'm hoping to maybe conquer my fears.:) Thanks for the help!
