Kakashi and Kakuzu win this mid diff at most
--Kakashi has more than enough speed and reflexes to compete with either of them, and his raikiri has shown to be superior to sasukes chidori, added to the fact that kakuzus fuuton can counter sasukes raitons, means that sasuke is not doing shit here
--Tsunades attacks are evaded by both of them, as kakuzu can use his katon+fuutons to attack her, whilst kakashi can get a chance of taking her in on genjutsu,
--With sasukes summonings restricted, and with his raitons negated by fuutons, means that he has no way of atttacking kakuzu at all, and resorting to CQC is getting him overwhelmed by domu based attacks, and tendrils, he is getting overwhelmed just how kakashi did in canon
