As far as the movie series, I gotta go with Star Wars. Yeah, the prequels are... er... oookay, but the original trilogy is just a classic. The Harry Potter movies are great though (well, 1 & 2 havent' stood the test of time in my opinion... relying on three 11 year olds as the main actors in a film is risky business.), and getting better and better. Can't wait for Deathly Hallows Part 2!
As far as the book series goes, Harry Potter all the way. 
But yeah... Star Wars, Lord of the Rings, and Harry Potter are probably my favorite fictional universes ever... so I've got love for 'em all.
