Countdown pretty much over and it was a terrible comic to the point where it's hilarious. DC has essentially acknowledged that Countdown did not accomplish what it set out to do (be the "spine" of the DCU). And even so, Countdown is an ensemble book; to be honest, Kyle was just along for the ride and not really one of the movers or shakers. That honor ( ) goes to Jason, Holly and Harley, Mary, Solomon, Darkseid, Jimmy, and near the end, Ray.
GL is one of DC's strongest, most important titles right now, and Hal is the focus of that. Hell the current storyline is a retelling of Hal's origin story. If we're talking about going with current events, Hal Jordan is definitely the GL to go with.
