Anyways, the Jedi Exile has the ability to drain the force from her enemies. It has been shown to work on different Jedi masters (Vrook, Kavar, and Zez Kai). This has been shown used by the DS Exile, so it is fair extrapolation that the LS Jedi Exile can also use this unique ability, but did not because the powerful opponent's she fought were anomalies of the force much like herself (ie, Nihilus and Sion)
Windu has her either tied or beaten in terms of lightsaber skills. Because of her special ability though, I can also see the Jedi Exile winning this battle.
I'd give it to Mace. He as has been noted has Vaapad and his skill with Shatterpoints. He's also said to be on par with Yoda in the Databank(Though what exactly on par means is debateable.) He also took down Sidious who the NEC calls "the most powerful Sith Lord in history."
The Exile wouldn't have her drain as it's a Dark Side power and the Light Side ending is what's Canon and otherwise she's not preticuarly exceptional and to beat Mace at his own game you have to be.
