No Madara and hashirama has more skills than gai even in cqc. The whole theme of my thread is that not having O.P , super-powerful jutsu doesn't mean you can't defeat a much stronger opponents. You can always rely on conventional weapons to defeat a stronger opponents if you have skills and brain to do that .Does this mean gai can defeat madara or hashirama because he is better @ cqc?
Most people would be laughing as hell if some 1 said 100 manga episode before that hashirama can kill madara by sword but We know now for sure that sword mortally wounded madara.
Hence the point is , Minato being my favorite character can easily kill Madara,Hashirama or etc if he can land a direct rashingan hit or a kunai slash/stab .
