Okay,first of all,people should stop comparing madara's fighting style to sasuke. Yes,his susanoo is stronger physically,but he does not make extensive use of ama like sasuke,hell,he hasnt even used ama in the entire time he has been here,ama isnt part of his fighting style.
Sasuke can cover his susanoo with enton,hashi's moukton needs to make physical contact with his susanoo to do any good,enton will destroy any wood around,and he can manipulate it in form of a sword,his arrows as well posses ama flames.
Even if hashi wins,it is not going to be low diff at all. It would be mid-high diff. Sasuke even has his chance to win.
