I actually like Brabant more than Holland for forming Netherlands. You have some advantages, namely that you don't start in a PU, have 3 provinces, and get female rulers so you don't get become emperor missions. My general strategy is too get early vassals, and hopefully a PU. If you can get 2-3 vassals and some allies, even opms, you can beat Burgundy. Especially if you can deny them Hainaut, Liege, and Luxemburg, as they aren't that strong day 1. For Burgundy, when they come at you, get maybe 14 soldiers, and mint to go over your limits, get a general. Let their armies siege your province, and after they go to assault your provinces you move in and take out their armies. I then siege them with the help of your vassals and hopefully take Antwerp for your troubles. To form Netherlands PUs are best. As soon as Holland breaks their PU you PU them, then try to PU friesland and Gelre.
Oh, I just liked this post. Playing Brabant you will get the Flanders culture provinces within the Netherlands, which is just nice. Not sure though what to do with the Wallonians but often it's France who removes the problem completely.
