Doesn't matter which one it is, it's all the same. Giant green fist and green lasers. Sinestro's making giant gold energy dragons that eat tanks, and all the Green Lantern can do is the same old bloody green lasers.
It makes you wonder if the Green Lantern Corps deliberatly look for that when they're out picking people. "No, no, this one's displaying way too much creativity. Nope, nope, that one had problem solving skills. Send me somebody who can only think in terms of fists and lasers! Possibly related to the Wonder Twins!"
I suppose it's possible they had cleverer Green Lanterns in some of the comics, but I am not impressed.
