yea, but Ysshin is very strong as well... we can roughly tell the power level of Kisuke by the people he hangs out with, Yorouichi on the other hand might have some tricks up her sleeve, i mean she can throw knives from her feet
The reason i go for Yoruichi is she was a captain before Kisuke, so he has more experience and Kisuke even served under her at one time and the more experience captains ae usually the strongest just look at yamamoto, Shunsui and Ukitake, although i dont think the gap is that different between Kisuke and Yoruichi. In a fight Yoruichi has this she is a better hand to hand fighter, she was the captain of the second division and of the special forces and also she uses his hand to hand, she made Yammy look like a fool when Kisuke needed his Zanpakuto to do that. Also she is faster...........Goddess of flash anyone, she is faster than even Byakuya, and taught him everything he knows. I just think Youruichi edges it in the physical department but i can see Kisuke comng up with a plan afterall he is smart.
The annoying thing in Bleach is always the element of surprise that Tite Kubo uses to make short-cuts in battles e.g. the sickening battle between Ichigo and Ulqiorra, the Arrancar had this pr!ck at the ropes and yes he KILLED ichigo once, then all of a sudden DEVILMAN ulqiorra got curbstomped by some looney in a paper mache mask with no apparent explanations - worst thing is that Ulqiorra didn't die with a bang
Plus experience would not be a factor in these fights i guess, it is surprise
