For me, it is between Kirk and Picard. I don't care about Janeway, because I hated the actress, and Deep Space Nine really never interested me.
Kirk was fascinating and adventuresome, flawed, allowing for the Vulcan to correct him and help him in situations while he had some woman's panties hanging from his ear.
Picard seemed to be more experienced, reclusive and educated. The old man captain. He was ultimately the decision-maker, taking advice from a robot, a blind dude, a hot-headed Klingon, and some bearded guy. He was the diplomat explorer. Something of a philosopher. When the Borg captured him and used his mind to wipe out the fleet, it showed how what he was capable of. I guess.
I suppose Kirk had more personality, and was more enjoyable in the films, but as a Captain, taking care of a crew, I think Picard was the better. It's close though. Different men.
