looks like im the only one to vote different.

my governors are always chosen by what the provience has to offer, not what the governer can offer. If the provience is one of my chief income proviences, then ill will give them a high acumen governor. If though it is a provience not so good with money (inland ones) then i chose the governeors based on the titles bonuses.. say the bonus is +2 loyalty, ill go find my most disloyal general, and give him the title. If the bonus is +1 to command or something similar, then i will give it to my better generals. If the bonus is dread, then i will give it to a unit of knights with high dread. It just makes it a lot nicer knowing that your 4 star general can easily get to 9 star with the right titles.
