Roronoa Zoro vs. Citan Uzuki

Considering some of the ridiculous shit we've seen both do, I think I still have to give this one to Citan. He won't match Zoro in terms of physical strength, but his intelligence and agility are significantly higher; Zoro likely also wins in the endurance department. That being said, Citan is a very cerebral sort of fighter. He would assess Zoro as having the edge in a direct confrontation almost immediately, and begin using his ludicrously high intellect coupled with his crazy speed/agility to eek out a win.
