Even though Universal has a rep of being a coaster park,all they really have are Hulk,Dueling Dragons which technically are 2 different coasters,Revenge of the Mummy,the smaller Flying Unicorn and the Woody Woodpecker kiddie coaster,so they're not a Cedar Point with 13 coasters but the ones they have are really good.Aside from the coasters at IOA I would also suggest riding Spiderman,the 3 water rides at IOA(Popeye,Jurassic park and Dudley Do-Right),and Dr.Doom which is fun but quick.At Universal you have the Classics like Jaws,the renovated Earthquake now called Disaster,Terminator and Shrek are fun interactive 3-D rides,Twister is OK if you've never done it before.Men in Black is an addicting shooting ride in a spinning car,I ride it like 4 or 5 times in a row to better my score.Also the new Simpson's ride will probably be opening around April so you might get lucky.Overall it's 2 great parks but as far as coasters make sure you do the Dragons,Hulk and Mummy.
