Actually, Shikamaru lacks overall ability.
Kakashi technically lacks stamina but he is still a very powerful Jounin because he compensates his lack of stamina with all his other skills whereas Shikamaru only has his intellect.
Edit: I have to agree with a previous poster; Kakuzu and Hidan have showed very little battle tactics. I suppose since they are considered to be the "immortal" duo, they usually use their brute power to kill their enemies. I personally can't wait to see Naruto's development ... everyone was bitching about how little he has progressed compared to Saskue.
