I got a 24mm SynBad Fan knot. I primarily face/head lather and am a Arko fan, using it in stick form. For that, it's a great knot. And it's very gentle on my sensitive skin. But it is not a Jack of all trades, and you should make a different selection if you puck load or like some scrub.
My only complaint is that it's a HUGE lather hog. I have never met a greedier brush.
