Let's look at the negatives, shall we?:
1. Sasuke could care less about most anyone's opinions
2. Sasuke has done violent acts of crime
3. Sasuke gets pissed quickly
Naruto:
1. He's not that bright, so paper work is going to suck.
2. He probably won't do the dark part of his job, like Hiruzen didn't.
Let's look at the positives
1. Sasuke is smarter
2. Sasuke would do both parts of the Hokage job (Danzo's and Hiruzen's, like Tobirama did).
3. Sasuke would want to change the village for the better.
4. If he becomes Hokage, it'll prove Kishi's point that people really can change.
5. He's freaking strong.
1. Naruto genuinely cares for the village.
2. Tsunade wants him to be hokage.
3. He's built many friendships with villagers of his own, and other villages.
4. He's freaking strong.
Going by this, they both have their qualities. So, like I've said in my own thread, if they both became Hokage (at the same time) they cancel all their bad traits out. But that wouldn't work well.
They both have their merits, but Naruto deserves it more,
