Kyle Rayner was the first GL I read, in Morrison's JLA, so he'll always have a special place in my heart. Same with Wally West and the Waid/Johns Flash. Hal Jordan and Barry Allen I hardly care about.
That said, Green Lantern: New Guardians sucked ass, at least in the first few issues I read. Strangely, I think Green Lantern Corps. is the strongest of the current Lantern titles, and it focuses on characters that I've never read about before. Surprised me.
