The Savage Dragon has constantly been one of my favorite comics since I was in Junior High.
Like others said, Invincible and Walking Dead are high on the reading list as well. Invincible especially because the art is so good! It constantly takes all classic superhero tropes and spins them on their ear!
Fables is great. The concept and characters are fantastic, and the build to the whole first big story arc was great storytelling.
The first volume of Wolverine & The X-Men by Jason Aaron and (mostly) Nick Bradshaw was a lot of fun, and I've been digging the new Posehn/Duggan Deadpool.
Classic favorites include the original Mirage run of Teenage Mutant Ninja Turtles (although the new IDW book is pretty good as well), Dragonball/Dragonball Z, Preacher, Paul Grist's Kane, Hellboy/B.P.R.D., Bone...Man, I could go on and on.
It all depends on the kind of stuff you're into!
