Jean-luc was less a pirate than Kirk. What I meant was that Star Trek captains tended to play the role as a swash-buckler, a free-lancer, a
I'll make the decisions around here", kind of character.
There are two different things there. If you are saying that she was a better leader - that she ruled by consensus and took people along with her ideas, then yes, she had to do that because of the Maquis. She listened, weighed up arguments and made a decision that was not 'off-the-cuff'.
However, I disagree about the 'pirate like' 'free-lancing' aspect as that is realistic for a Captain on a 'Voyage of Discovery' like Kirk and the Enterprise were supposedly. They were meant to be at the far ends of known space, 'where no man has gone before', far from home, without supply lines or any back-up. Gene Roddenberry saw it as a 'waggon trail in space'. I equate it more with Captain James Cook and HMS Endeavour. The number one priority
must be survival at all costs, whatever Starfleet says is the Prime Directive. (Unfortunately, this idea was confused by having them meet with old Earth colonies almost every week.)
Jean-Luc didn't need to be like that. He was captain of a much larger flagship of Starfleet and all corners of the Alpha and Beta Quadrants were mapped out. They rarely made first contacts missions, it was more rescues and investigations. So, why he still got involved in 'cowboy diplomacy' I couldn't say.
Janeway ought to have been much more like Kirk. She really was completely alone. Every contact ought to have been a first contact. She had no supply lines at all, no back up, no way to return home. So, you may think she behaved more 'captain-like', observed the Prime Directive better and was a better leader, but she should have been more 'pirate-like'. I don't think Janeway should have survived in the Delta Quadrant. They should never have got beyond the 'year of hell'.
