I personally think Queen Fen should be on this list.
But otherwise, they all have their strengths and weaknesses as leaders. Dalinar, with his experience on the battlefield and in general life, has the capacity to see things from a broader and more long-term perspective than Kaladin, who has natural leadership potential but is too young to have as much experience as Dalinar. That being said, both of these men are soldiers, and both lack the political perspective of Jasnah or Sarene.
Jasnah and Kelsier are both willing to sacrifice lives for their own cause, and this ruthlessness is useful during the times in which their respective books are set, due to dire circumstances. Both are very intelligent and aware of the significance of their cause, and the role that they play in politics and society. They both act as icons for their own beliefs, and hold a certain degree of power over the people. However, in the long run, both lack the overall compassion that we see in Raoden that makes a good leader.
Raoden was raised in the court, and thus has significant knowledge of the political climate regarding Arelon. He is able to take a minority and empower them through tactfully removing his opponents to regain control and inspire his people. He, like Elend, cares for the lives of people and tries to see the motives behind people's actions and situations before judging them. Based off what we have seen in the Cosmere books so far, I would have to say that Raoden or Sarene make the more well-rounded leaders, although Jasnah would be the best leader in current situations.
But Queen Fen. Enough said there.
