Yeah, apart from the fact that this has been done before, it'd be close, I don't know if Maul could have done as good as Asajj did against Obsession kenobi, which is Kenobi just 5 months before ROTS, but then again, I can't see Asajj resisting a Force Lightning attack like Maul did in the comic where he pwns the entire Black Sun Syndicate and I also can't see her doing as good against both TPM Obi-Wan and Qui-Gon 2 on 1 as Maul did, I mean, Qui-Gon was one of the Order's finest swordsmen and, as Advent pointed out to me, if took Maal only 30 seconds to kill Qui-Gon after the energy doors opened and that was when Qui-Gon was attacking with a ferocity not seen before and had a new reserve of energy from meditation, so I'll go with Maul, unless he makes a mistake like he did when fighting Obi-Wan, but I can't see him underestimating an opponent as strong as Asajj Ventress.
