If you could choose between these two brushes, which one would you choose, and why? I'm looking at getting one or the other. For reference, I have 3 Simpson brushes in Best and an Emperor 3 in Super (that I haven't used yet). Is the Chubby 3 too large? Would I be selling myself short by settling for the smaller Chubby 2? Is there much difference between the Best and Super knots?
