Soara's apparently much faster than Obi and Siri combined and has apparently surpassed Obi-Wan.
Meanwhile Siri is noted as being Obi-Wan's peer in JQ and post AOTC, this is further reinforced by the Jedi vs Sith Essential Guide, which states that Siri was Obi's Compatriot.
It's hard to say really, Xanatos has done extremely well against Qui-Gon and Obi-Wan(he nearly killed Jinn on bandomeer according to a Fact File) and is a master duelist.
I don't know, this vexes me quite a bit. Either way it's a good fight with the winner getting a 6/10 majority.
If I recall, wasn't the reason Xanatos lost to Qui Gon due primarily to his sub-par footwork? If so, does anyone think that this weakness has any bearing on this match?
I don't believe his foot work was mentioned in Reckoning(the last book in the Xanatos arc). it is, however, mentioned in Captive Temple wherein Jinn confronts Xanatos and taunts him.
However my memory is a bit iffy on that, given that i read all the JA novels, so i'm not sure.
