Basing this on chapter 641. I think this is the second time someone hyped Shikamaru up as Hokage. Which is a much bigger deal than declaring yourself a Hokage candidate like Sakura or Kiba. Now you can say they were Asuma, his teacher, and Temari, who is now in love with him, but Kishi clearly believes he is worthy of the Hokage title. Or he wouldn't have bothered with those panels.
Sasuke - Has the power required to be Hokage. While not in Shikamaru's league, he is intelligent and has a good strategic mind. Having an Uchiha Hokage might right some of the wrongs in the past. Then everything falls apart. He doesn't care what others think. He doesn't have the power to change hearts. He is not a good leader. He is too impulsive and selfish. He still plans to betray Naruto and set up his own system.
Shikamaru - He lacks some of the power required, but has already proven his talent against the Akatsuki and during the war. Smartest guy in the manga. No one can challenge his intellect. Makes the right decisions. Values the opinion of others. Great leader. Master strategist. Can change hearts with his words. Cool and calm. Never panics. Not power hungry. Trusts Naruto.
Who would be better for Konoha?
