Green Lanterns are my favorite heroes. I started reading comics when I was about 4, as my dad was into the Death of Superman, KnightFall, and Zero Hour, which were out at the time. I saw Superman's fall, Hal Jordan's fall, and Batman's fall. Then I saw the Reign of the Supermen, Azrael, and Kyle Rayner rise.
So my favorite is Kyle. He's always made cool-looking constructs with his ring. Hal's always made simple things, like hammers, and fists. They work, but they sure aren't cool.
