I have used a bread machine to make my pizza dough, and I have also used a Kitechen Aid planetary mixer. I definitely prefer the bread machine for making my pizza dough. For some reason, the dough always seems to get hung up on the dough hook of the mixer, and I don't get the impression that it kneads thoroughly. I never have these issues with the bread maker. Additionally, it seems like there is nearly zero waste (bowl residue or whatever) in the bread maker. I also use my bread maker on the dough setting, but I don't ever let it go for more than 20 minutes (maximum). I allow it to knead, and when the dough ball takes on a smooth and satiny look, I stop the machine and form a tight dough ball, oil it, and let it rise (retarded in the fridge, or on the counter when I'm making an "emergency" dough, a.k.a. lack of planning).
