Hey CZ...I'll weigh in just because I've got two 22mm SilverTips from whipped dog. They are super soft and will build and hold a nice lather. Unfortunately, I can only compare it to the Finest and the Black at TGN.

It is dramatically softer than the Black badger, which is extremely prickly, but stiff.
The whipped dog knot is a joy to face lather but no slouch in the bowl either.
Hope that helps. I know there are guys at B&B that have used some of the other knots from TGN, so hopefully they will chime in.
I tried a MMOC once. I've sinced switched to straight razor shaving because it was less dangerous.
