kimimaru healthy could be a top 15 fighter...he was fast and top 10 most durable if not top 5 because few shinobi even the raijage cant survive repeated sand burials/sand coffins like he did...lee even said kimimaru was a taijutsu master saying he had no wasted movements, and his taijutsu was so good they were called dances...brackence dance, clamatis dance and etc., and kabuto said kimimaru was already dead and that he was willing himself to fight...if he was considered a master while already being dead and his cells corroding then and perfect health kimimaru would probably be the best in taijutsu...and we got to see some of his skills with his edo self in the war, and proof of his prowess comes from him being one of the remaining edo's before itachi released edo tensei...
