yes taijutsu vs taijutsu but you have to remember that kimimaru also has cursed lvl 2 seal and well reall all lee has is his super great taijutsu kimi can use nin and prolly gen jutsu

but all in all i think rock lee will lose and be back where he started "in the hospital" just my opinion im not a huge lee fan but he is a great character and should win i just don't think he can do it
