Minato would probably do the best because of FTG + Rasengan technique and can just do that and I'm sure he knows more than that like his sealing. Or Hashirama would because we've seen part of his power through Madara and I think Madara uses it differently/weaker than Hashirama ( Am a Madara fanboy so no hate please).
The Next Candidate For Hokage besides Naruto out of the K11 would probably be Shikamaru or Lee.
Shikamaru for his genius, his strategic battle experience, his Shadow Possession Justu, among other things.
Lee for his Springtime Of Youth (His version of The Will Of Fire), his enthusiastic attitude, hard work, Gates, and much more the only thing that would hold him back is the fact that he's never led a mission.
Lol Ignore The First Paragraph.
OT: Oonoki or A would do the best or Gaara lol.
