ur forgetting madara was also a genius and his s/t was like there were tags in evry single spot of existence.i think if that fight really happened madara would have to "somehow" kill him fast because 4th is a genuis and throughout the battle he would be planting toattoes all over so if madara wasn't watching where he steps it's game over
Actually, I still don't consider Madara's a S/T just yet.. they just said he moved at the speed of light, which doesn't exactly mean S/T.. The way I look at it is that Yondaime was probably the fastest being able to do true S/T, while Madara (and Shisui for that matter) were just so fast it seemed like S/T.ur forgetting madara was also a genius and his s/t was like there were tags in evry single spot of existence.
It was exactly the same as yondaimes just without the seals and handsigns. So its a lot better.
