Anyone who says Naruto should shoot themselves in the head, then they should be violently skull&%$* until what's let of their retard brain is a mixture of %&$ and ^%*$.The OP asked who is the "most qualified", not who you like the most or who is the strongest.You take away strength from Naruto and he doesn't meet any of the qualifications to be a leader of any village, yet alone the original shinobi village.
If someone nees an advisor for every single task he has to make, then what's the point of him being the leader.All the previous Hokage were able to make decisions solely on their own thoughts.They all made some goods decision and some bad decisions, but they made decision on there own.At this point, Naruto would be nothing more than a figure help while everyone around him ran the village.As for the person who said it only takes will to be a Kage, Idealistic nonsense like that is what separate the great nations from the slums.
