I feel Windu takes this.
In the cave of despair, there would far too little space for Vader and Maul to cohesively work as a unit.
This also means that Maul's acrobatics won't save him from Windu. Mace could easily use his shatter point ability to take down Maul.
Vader's choke would be a problem, but Mace could use force crush to counter this (screw up Vader's life support system). He is also Maul's superiour in force techniques so he could throw Maul around without any difficulty.
The duo could pull it off but I doubt it. I would put it at 60/40
