Technical ability reigns supreme, this includes accuracy, speed, complexity, and overall control. Versatility isn't important unless there's a tie between two players, where versatility can be taken into account. Beyond that, I don't see a need to include any other criteria. The knowledge of the editor and the other members should be enough to figure out who should be ahead of whom. After the guitarists names you'll find links to tunes that are representative of their chops.
