Doou possesed considerable skill in Makashi as well as skill in most of the other classical forms; coaching of Grievous in lightsaber arts and threatened to demonstrate techniques of Yoda, Mace and Obi-Wan, not to mention he was a lightsaber instructor during some of his time in the Order. Also, while Djem So affords its practitioner a natural edge over Makashi practitioners, Dooku similarly capitalized on its weakness against Anakin: lack of agility. While Bane is physically strong, he favored a more ''subtle'' approach as his body began to wane, not the head-to-head attacks Anakin utilized when he beat Dooku on the Invisible Hand (and he also lacks Anakin's Force energies to call on). So, lightsaber skill should be in Dooku's favor. In Force mastery, perhaps Bane's learnings are more in-depth, but Dooku's study lasted for several more decades (''the most learned in the ways of the Force'', as Yoda put it). He also has a better résumé of Force feats. Dooku wins here as well. Overall, good fight, but Dooku enjoys longer time spent refining his skill and studying the Force. He wins.
