:flaw:The Flying Thunder God technique does indeed seem to be somewhat faster than Madara's space-time ninjutsu. But it also has its limitations; and if we're talking about Minato and Madara, then many seem to forget that the Flying Thunder God technique is worthless in front of Izanagi. No matter how fast a ninja Minato is, if he has no clue as to what the forbidden illusion is (and it is very likely he does not), then he knows no counter to it, and will have a major problem on his hands. But Izanagi aside, just because Minato's Flying Thunder God technique seems to be faster than Madara's space-time ninjutsu, doesn't necessarily mean it is better.
You see, it was not so much Minato's victory in chapters 502 and 503, but rather Madara's error. He did not know there was a second level to the Flying Thunder God technique, and it was that one mistake that Minato took great advantage of, allowing him to delay Madara and his plans for a certain time. But even still, both techniques are extraordinary creations, and I enjoyed seeing them used in action.
Well when you say that Minato didn't really win but it was madara's mistake that he lost against the Fourth .
Well then you can also say that Kisame lost because it was his mistake and not Gay's strength and about his technique .
You can also say that Konan lost because it was her fault that he she didn't know about Izanagi .
