I'm giving it to Obi's team. Obi wasn't that far behind mace in skill. So assuming Ani doesn't get owned real fast and provides somewhat of a distraction Obi takes him down.

there is no Obi team. it's free for all as far as i can tell so ganging up on him might not be an option. Also, i'm not sure which one is better, i know Mace was considered second in power to yoda and that he was one of the best (if not THE best lightsaber duelists in the galaxy). However, Obi Wan's defensive saber style might prove to be the best tool against Mace's vicious Vaapad style. I see a few outcomes:
1. Obi Wan starts facing Mace. Mace is winning so Anakin does some crap like in the movie to chop Mace up knowing he's stronger than Obi Wan.
1a. Obi Wan faces Anakin and beats his @ss again most likely.
2. Anakin starts facing Mace. Mace is winning so Obi Wan pulls some crap so that he can fight Anakin (too sleepy for a reason but i think that would happen).
2a. Obi Wan faces Anakin and beats his @ss again most likely.
3. Anakin starts facing Obi Wan. Mace watches....he wins this one no doubt.
So basically that's how i see things, but...that's just my point of view.
