Whitout a source of water and whith a healthy Kimimaro, Kimi outlasts him, since he dehidrates after a prolonged battle and lose...
Otherwise A sick Kimi would fall first.
unlike suigetsu, he needs no source to use ninjutsu. he also mastered the curse seal of earth while suigetsu is known to be a lightweight & has a natural frailty outside his element.
I really don't get the point of pitting a person that has been explicitly stated to be immune to normal taijutsu against a person that uses explicitly normal taijutsu.
