"Sisko is the natural "get it done" guy. He's the one you want if you've got a lot of things happening all at once, and they are happening fast, and you need results. He had a space station to rebuild and then run, a people to be an Emissary to, wormhole aliens to deal with, The Dominion war and all that that entailed, plus a son to raise on top of it. He's more or less like, "I've got a schedule to keep, so this is what I/we can do for you, now what can you do for me/us?" Sisko is ideal for when the $%#! is hitting the fan."
I agree wholeheartedly. Picard would be be my second choice...and I'm not sure I would nave a third choice. I wasn't really feeling any of the other Captains...I often found their actions annoying rather than inspiring.
