I agree I think Minatos best chance is because he already knows about Madara cause his name went down in history yet Madara knows nothing of Minato so he could underestimate him and think hes a puppy, yet I still think Madara would win in a fight to the deaththe thing is, in my personal opinion..in terms of jutsu's madara is in another league but minato just like itachi, sasuke, shikamaru and kakashi are very good analysts and that is what would give minato the upper hand though i still think that they can take eac other head on and there becoming a different victor at each different battle
