I'd have to say Picard. Out of all of them, he is the least likely to throw away the lives of subordinates on some fool's errand. I would trust him more than any other of those captains, not to get me killed.
The *least* likely for me to serve with? NuKirk. I realize he's young, but he's also an immature jackass (i.e. the bar fight) who jumped in rank from Lieutenant to Captain without deserving it. No way would I ever serve under his command.
