I don't think madara wins against Minato. What keeps Minato from teleporting Madara under chibaku tensei's coverage? Can Madara escape when pulled into the sphere? Does he have space time techniques that can help him with that? Minato need not to teleport Chibaku Tensei but instead teleport Madara so he can be pulled by his own jutsu. As we all know, Minato can't be trapped because of his technique.
For shinra tensei, what will Madara do if Minato throws a kunai 80 degrees above and throws another one at either sides after throwing the first one? Which kunai will he repel? In this battle, Madara will resort in using sharingan techniques. Everyone would say that Minato can't do nothing against susanoo. Does he really need to break the defense? If your wise enough then you won't recklessly use your chakra knowing you are facing an elite shinobi. How long can Madara activate his susanoo until he runs out of chakra?
The more jutsu Madara uses then the faster his chakra depletes. Minato will take advantage of this and attack once susanoo is deactivated. Now, ask yourself with this..How can Madara defend Minato's attack without susanoo? Shinra tensei is not effective against Minato because it has a cooldown and like I said, Minato can throw multiple kunais at different directions.
