Kind of a day late, but I'm kinda rusty in terms of posting. Anyways, my Favorite Green Lantern isn't Hal Jordan. It's Kyle Rayner.
I know he's still considered "The New Green Lantern" by most, with Hal Jordan still seen as "The Real Green Lantern", and to be honest I never really followed his main title. But I did follow Grant Morrison's "Big Seven" JLA title, where Kyle was the resident Green Lantern, and he really impressed me on that title.
Can't find that many scans, though, but here's one that impressed me: Kyle "Growing up" and telling Guy Gardner who he is.
