Think about it. Sasuke isn't seeking acknowledgement, he's seeking to change the system. Has Naruto's goal even shifted that much from simply gaining acknowledgement and offering a ridiculously axiomatic panacea for peace?
I'm not attempting to say which one would make a better Hokage, I'm simply stating that Sasuke's reasons are better; he thinks the current system is twisted and broken beyond repair, and he's attempting to create an entirely new one. He seems to have a direct plan for making his reasons a reality, and his overall personality seems to just fit.
