That really depends on the position and leadership style. Teft has caught up to Kaladin in terms of oaths but he is not exactly a likable person personally. Spensa notes that Cob is very difficult to work with yet he is very admired leader.
Dalinar is both unavailable as a leader of alethkar and proved to be kind of bad at it in certain respects. He made a number or mistakes that Jasnah would probably not have(Trusting Sadeas and Ameram, publicly refounding the radiants, the entire mess with his nephew just to name a few). I do not think that Jasnah is completely without problems but in terms of experience and other more measurable forms of ranking candidates she tends to come out on top.
