I went with 'The Sisko'.
He has all of the best of Kirk and Picard rolled into one deep, driven officer. Kirk is the captain I would've loved to serve under when i was younger, maybe as an admiral I would love to have a Picard on my staff....
But now I would feel the most confident in Sisko, he was bad ass when he needed to be and accessible when you needed him to be. Just look at the 'Seige of Ar-558'. A classic episode I would cite to why I would serve with him.
