My vote's personally so far:
1: Daanor: He is always checking for timed out house owners, answering all questions, welcoming new players, and is very helpful. Only thing is, he needs to be a little more active.
2: Prodigy39: He's great at solving arguments, and excellent on answering questions.
3: lilwaffles: Before he was a decent moderator, but recently he's been stepping it up with helping others. He just needs to keep this up.
4: ArchieSalt: He's been more active lately, But i don't see him help anyone. the only thing i see him do as a moderator is hosting elite fights.
