How would Minato get through Susano'o? And don't say that he puts a seal on Sasuke before he activates it, 'cause Sasuke could activate it straight away? I don't think that his rasengan is enough powerful to break Susano'o and also Sasuke has Amaterasu shield.
Also if Minato throws Kunais everywhere, Sasuke could destroy them with explosion tags, fire element jutsus etc.
If Minato doesn't know about Sasuke's Tsukiyomi, he's screwed. When Minato was against Tobi, he looked at his face all the time, even though he knew he's Uchiha. When he makes strategy, he usually looks at his enemy and if he would do that against Sasuke, he's under Sasuke's genjutsu and is incapable to move. And that way Sasuke could easily finish him off.
I'm not saying that Sasuke would definately win, I'm saying that they both have as good chances in winning. Also people have only written about Minato's advantages, so I wrote a little about Sasuke's advantages.
