neither would be winning this through force powers imo, so it would likely get to a lightsaber duel, where maul easily takes this:
he nearly defeated darth fricking sidious in a lightsaber duel before he had even become a true dark lord of the sith (albeit he was in a rage),
he outclassed anoon bondara, someone whos skills were 'second to none' and 'unparralelled' to such a degree that he knew he couldnt win the duel pretty much as soon as it started,
while fatigued and not at his full power he was able to dominate against both qui-gon (who was outright stated to be on par with mace windu, and was the most talented swordsman his lightsaber instructor had trained in over 400 years of teaching the jedi order (likely Yoda)) and obi-wan (who was right at the end of his padawanship, and as talented as they come), and then subsequently own qui-gon (who had been fully regenerated) in about half a minute.
quinlans best feats were achieved either through luck and/or his opponent getting cocky, such as against sora bulq, where he was getting his ass kicked the entire duel, and got one lucky hit on sora right at the end, and he was getting seriously outclassed by agen kolar at one stage, who id not even put on anoons level, yet maul made him his b1tch
maul ftw
The Anoon quote, specifically.
And last I checked, he didn't "defeat" Obi-Wan and Qui-Gon. I give him f*cking up Qui0Gon something fierce, but I seem to remember Obi-Wan, after getting pissed, going to-to-toe with Maul, overwhelming and slicing Maul's saber in half, then chopping him in half five minutes later.
As for Sideous I didn't read the book, but did Sideous or whoever say if he was using the force or not?
Well, that's not exactly true. Kenobi overwhelmed Maul for a few seconds because of his anger and rage, but shortly after Maul takes control and Force pushes him out of the way and right into the pit. And, he could've actually killed Kenobi easily in that moment, but the fool decided to play with him instead.
I'm wondering, how? And people seem to have this belief that when Obi-Wan WTF pwns Maul with his saber it's "Maul getting surprised", yet when Obi-Wan gets force pushed out of seemingly no were it's "OMG Obi-Wan is t3h suxx0rz!". And Obi-Wan geting force pushed says nothing for his bladework. I'll look up the source when I get home, but Obi-Wan was also quoted to be an exceptional padawan.
