@Marco Makes a good point about the arrival of good synthetics from China. Many prefer the softest knot they can find, and synthetics are softer than any natural brush, hold more water, are more durable, and are faster to lather in general.
Some find the European STF to be a great synthetic, but I have two of them, and I don't think they are any better than most of the identified Chinese knots like cashmere, cat whisker, timber wolf, g5c, a2s, and others. Even the unidentified knots in $4 Yaqi Special Offer Defect synthetic brushes have some objective advantages over the most fancy and expensive badger knot ever tied.
Personally, I prefer some scritch on my soap and again on my face, so I prefer natural brushes overall. However, the brushes I prefer are the cheapest and lowest graded ones, boar, pure badger, black badger.
If I preferred a softer touch, my favorite natural brushes would be the Manchurian, the silvertip, the three band, the high mountain, but above all of these in softness would be the cat whisker, the cashmere, the STF, and other synthetics. Even the cheap synthetics fall between the best natural badger and the premium synthetics on this scale.
There is something to be said for the quality of the Chinese resin handles, too. Yaqi, Boti, FS, DSC, have gorgeous handles at rock bottom prices.
As an American, their AliX stores also provide a better shopping experience than I can find for something like Plisson, or Simpson. They have huge selections, great organization and pictures, exciting sales, special editions for youtubers and holidays, choice shipping, tremendous availability inventory. When I go to Plisson, where I would actually like to buy the gold and brass handled black badger or the ivory acetate Russian gray, they don't have either one in stock, they are $100-600, they want $29 euros for shipping, the VAT and refund calculation and currency conversion are confusing... it is painful so I don't buy them or anything else. I can get the Yaqi Sagrada Familia Pure Badger and the DSC Amber pure badger, two of my absolute favorites, BTW, for less than Plisson wants for shipping. Simpson is just as bad as Plisson.
