[Judge of the Year 2006's Vote]
I'm going to vote for the L.O.C.O. too. They just seemed to show a lot more offensive versatility while also having robust defenses. They also had the advantage of the addition of five Superman+ level constructs with GL rings. Demons were summoned in opposition but no substantial indication of their capabilities was given. It gave the impression of a numbers advantage. It also didn't help that KVD didn't get to post much.
Now about that cake...
