huge difference in the scale of attacks. Only reason why "hebi sasuke" is being favored in the thread, is because of the lack of feats from Sakura's side, as she never fought in a fight like Sasuke. So whether she wins or loses is based on assumptions from both sides.
But if we are to consider, her being able to break genjutsu (something she displayed in THE LAST), and her being able to react to things like Juubi's arm.... her physical prowess is easily above that of Sasuke's.. Sasuke also doesn't have any attack on the scale of Sakura, besides his Kirin.
