Always played under control of Ducth economics, but now I really like French pioneer, very good start can come out of him.
For English I have no need, because my early strategy includes taking over other colonies. Usually You are at the same continent with one (moderately close even), they'll go first. First colonies whereabouts arent that crucial, so I might build my core provinces up on their location.
Then next one on another continent, I also drag them to my colonies, if they don't have too good location.
When I'm after third one, they're usually stockaded allready, so I have to build up that place to became second core system...
Finally Spaniards -- I don't want to start killing off Indians, and
therefore they give me no boost in the beginning
