I like them all. Hal, John, Guy, Kyle, Alan... it doesn't really matter. I think there's a place for them all. They all offer something different to the ring.
Hal Jordan - What I liked about Hal was when compared to Clark Kent's All-American image, Bruce Wayne's charming playboy wit, or Barry Allen's remarkable intelligence, Hal (the death defying test pilot) was more daring and willing to take risks. Hal was also daring enough to challenge authority and his superiors on occasion (something Denny O'Neil picked up on and emphasized when he wrote GL/GA) and made him more of a rebel.
When Hal left the first time, it was because he had enough with his responsibilities, no longer saw eye to eye with The Guardians of the Universe, and just wanted to be with Carol.
The one thing I always got from Hal was that even though he was a superhero/cop his ideals/morals always came first. He was always kind of torn. Especially when it came to Carol Ferris/Star Sapphire.
Alan Scott - I always liked the mystery that surrounds his ring and powers. I wish they'd delve a little deeper into that.
John Stewart - I hate how they've misused him over the years. John's an architect and should be just as creative as Kyle but also more practical in his approach. Kyle is an artist (who tend to be about style and form) John as an architect should be about form and function.
Guy Gardner - The reason I like Guy as GL is because I related to him more than any other superhero. In a lot of ways me and Guy were alike. Guy used to hide his insecurities behind his gruff exterior and only his feelings for Ice made him get past that at times. Kind of like when I first had my accident (I broke my neck and am wheelchair bound now) I was a complete jerk to everyone I knew and cared about and I couldn't have cared less about it. Then there's the fact that Guy didn't always use his ring for good. I also kind of relate to this because when I got my settlement money I didn't exactly use it to benefit myself in a positive manner (sex, drugs, and rock n' roll baby) Then there's the fact he always felt under appreciated by his peers (even though he was one of the most powerful members of the League at that time) This I relate to as well. It's like some people think that just because I'm in a wheelchair that I'm totally helpless, and it ticks me off. I also liked how he played bad cop to Hal and John's good cop. He was such a hardcore badman GL (especially under Wolfman) and I liked the idea of him being "The Fist of The Guardians".
Kyle Rayner - The thing I like about Kyle is that he has fun with his ring (just like Hal did when he was younger) I don't really relate to him or anything but I do enjoy his creativity.
I just wish there were a few more Green Lantern books, because it makes more sense to me to create a GL franchise, than a Superman or Batman franchise (because Superman and Batman really only need two monthly books, and I find the amount of books they have is really diluting their concept, IMO. Where as, you could have multiple GL's each starring in their own monthly)
