User blog comment:Blackendedsoul/Doriki, level of physical strength or overall fighting ability?/@comment-1984061-20110522141244

im not sure but jyabura told kaku not to get arrogant because of the 20 difference as he still has the ability of his devil fruit (before kaku got his) which means it doesnt account for the zoan transformation boost.. also kakus transformation was very advantageous for a swordsman as stated by zoro.. but then again carnivorous zoan are better for hand to hand combat.
