Um, no. Kakashi is A-rank. Even in part 2 of the series, he was still A-rank. Albeit high A-rank, but still A. That's not to say he's not strong, cause obviously he is, but I just do see him being a S-rank shinobi.

I'm just saying this because he was considered to be the next hokage. 

And if Tsunade and Kakashi fought, I'd put my money on the latter. :hehe

P.S. Kakashi ANBU gaiden was so AWESOME!
