My first synthetic brush was a Parker which had a very small knot. (not sure what size but I would guess 19mm at the most.) Although I was happy with it I later bought a Jack Black brush that had a nice dense 24mm knot and I got so used to it I ended up giving away my Parker. I didn't like it anymore.
I find it better to make lather in a bowl with a bigger knot. I guess you can make anything work once you get used to it weather it's a brush, soap or razor.
