All the other Captains have done a great job but Sisko had to run a war. That puts him over the top.
Agreed, Prosecuting a war is never an easy task. Espically the Dominion war, when at time the Dominion had superior numbers, he got the Romulans into the war "In the Pale Moonlight" just in time. Admiral Ross needed his help and gave command of the Defient to Jadzia, all Capt's in Trek did really great things and some not so great things, this also goes for Sisko, however, my vote also goes to Sisko.
