The Green Scar was definitely my favorite incarnation of the Hulk. I enjoyed the title up until the recent numbering reset, but the recent Hulk v. Banner storyline has left me pretty thoroughly convinced that the Green Hulk needs to disappear for a bit.
The Hulk is a character that works best when he can be portrayed in large, impactful, world-shattering ways. Characters like him become less impactful the more we see of them, and the Hulk deserves to make a huge impact every time he comes onscreen.
Right now, we've had a LOT of Hulk exposure recently, between Planet Hulk, World War Hulk, War of the Hulks, the Red Hulk, etc. Banner is about as exposed as Tony Stark, Spider-Man, or Wolverine now, and his appearances less exciting for it. He's becoming an expectation; something big is happening, that means Hulk will be there. Instead of cheering ecstatically or grimacing in horror when he arrives on the scene, we just sort of expect it now.
He's done a LOT recently, and the current writer doesn't really seem to have much of an idea of where he should go now, and that's because most of his story angles have already been played out in recent memory. The best thing for him to do right now is fade into the background and wait for people to stop taking "The Hulk will arrive" as a given. Give it a few years, let people start really wondering what happened to the Hulk, and then make an explosive, game-changing comeback in the big Crossover Event of 2015 or 2016 (because we all know those aren't going anywhere any time soon).
