Scenario 1:
Windu struggled to use Vapaad on Haruun Kal because he was afraid of being overwhelmed by the Dark Side.
Maul in the cartoon ragdolled Kenobi with the force while Kenobi seemed to be the better lightsaber duelist. This was on neutral ground.
With these two facts, I can't see how the Jedi would win here.
Scenario 2:
Dooku vs Mace: I would guess Mace would win more often.
Maul vs Kenobi: This is more of an even split.
I'd say the Jedi would win at least 6/10.
Scenario 3:
In the TOR trailer, Malgus didn't seem to have too much of a problem fighting in the Jedi temple. But that was a different era, so I don't know.
I would guess the Jedi would win though.
