I didn't vote yet, so I don't know the most beloved captain.
In my opinion, Pirates 2009 are the worse Pirates series of all time, even worse than POTC.
The whole theme seems to be dedicated to kids, and completely not dedicated to adults or teenagers.
The skull on BrickBeard's hat looks extremely cartoonish comparing to the old skull which is a "real skull".
His torso is pretty nice indeed, but the epaulettes and the hook are horrible.
That shiny golden yellow makes the captain to look like a kitsch toy.
This color is one of the main reasons why I still prefer sets before 2002.
Also BrickBeard's face doesn't impress me at all.
His face is also extremely cartoonish, and eye catchy...
Honestly I admire much more the vintage minifigs (with the basic smiley face) due to their simplicity.
Being so simple, it makes them more universal and more collectible for collectors of all ages.
RedBeard? Not much to say about him...
Simple, accurate, elegant!
The first minfig with its own name.
I consider him maybe the best minifig of all time. (but not the best pirate captain).
Iron Hook seems to be the veteran of the pirates crew.
He lost one of his hands and one of his legs just as RedBeard, but his torso tells about him that he fought well each day, day after day.
Instead of wearing a coat, he has a simple shirt with a belt and a knife. (knife > maybe for backstabbing?)

A pirate like him cares about the treasure, not about the coat.

Also, a pirate like him doesn't care about epaulettes, everything being about gold and even more gold...
My vote goes to Iron Hook.

I think Brickbeard seems too much like an updated version of Roger/Beard, would be good if the LEGO Group could come up with something more unique for future Pirate sets.
True.

Well... at least he is not in the shadow of Captain Pete too.
