All I need to say is this, as long as Sasuke can make simple clones, or use substitution techs, he will win, Guy is all or nothing, he does a huge explosive technique, then is more hurt than orochimaru vs Sarutobi when oro loses his arms. As long as sasuke can last out, he can have no chakra, and take a kunai and kill him, dare I say it, he could press the easy button, then with a striking cliche, say "That was easy"
