id say kakashi for his because he has some skill in everything and more then some at most.... as for the others shikamaru because hes a badass and could come up with effective strats to use.... rock lee for his speed and taijutsu for scouting as well as fighting.... id say naruto as the powerhouse but he doesnt really fit so probably sasuke since he is consistently better then naruto except for the whole gaara thing i suppose and except for the whole itachi thing his emotions wouldnt get in the way or anything
