User blog comment:Goddess of Despair/Season 6 Battle 1 Darth Maul vs The Arbiter (Ripa 'Moramee)/@comment-4392864-20130824015423

Arby has a few weapons, along with that cloking ability. Also, he's trained in military tactics.

Maul, he has that lightstaff and the power of the Force.

I'd go with Maul- he could sense Arby's mind, and thus beat him.
