Sasuke has no chances of winning, he went blind in almost one friggin fight, no way his ms will allow him to have a drawn out battle with 6pop, and nagato can sense amaterasu, which is sasukes only real way of beating him, so it's pretty much a non factor. in all honesty chibaku tensei ends the round, and the 6 paths can counter anything sasuke can throw out.
Naruto would more than likely win since in sm he's a sensor, he has karin for healing, and with obito there, danzo won't risk using "it" on him since he's scared of obito joining the fray.
the rinnegan is kryptonite for sasuke, it counters all his main techniques with no trouble.
