I agree, the 4th Hokage does display some impressive skill and perhaps he is in some ways on par with Madara in regards to Space/Time Jutsu, however it should be pointed out that the 4th himself noted that Madaras S&T Jutsu exceed both his and the 2nds (didn't even know the 2nd could use it lol). What you have to remember is that Minato returns to the Village to seal the fox in Naruto so perhaps he does triumph over Madara in the fight, OH! and there is a second stage to his Thunder God Technique, perhaps he could travel at even greater speeds????
Your opinions?
I still think the 3rd Hokage is the best Hokage to date though, only because of the time in which he reigned, his reputation as the "professor" being known to have mastered every Konohagakure Ninjutsu and the fact that if you look back in his history there is nothing really special about him, he possesses no special abilities, no bloodline abilities, in fact aside from the death god sealing technique he learnt from the 4th he doesn't really possess any special nor outstanding jutsu, its all very basic elemental stuff, but he knows so much to keep his opponents in check.
