I'm an oldie who collects GA but on the other hand I am a big fan of Bagge (must get this series - how did I miss it?) Powell, Gray, and Palmiotti.
Some of the recommendations I'm not keen on for aesthetic reasons, such as the odd bit of artwork that reminds me of early 90s Image, but as long as there's a variance in art and storytelling then there'll always be something for me on the comic rack. The All-Star Western and Shadow series looked good, as did some of the Hulk stuff.
To be fair though I stopped my standing order five years ago as too much product, and there was so much of it, was samey while the visuals trumped the storytelling, which always came first when I started reading American comics (the early 70s). Comics should evolve but storytelling and characterization are more important than great artistry.
