This seems pretty accurate. Although I have yet to try the HMW yet and it just sits in my drawer... I'll take it out some day.I have a Yaqi two-band badger, silver tip, and high mountain white, all as 24mm but all in different handles. Of the three, my clear favorite is the two-band badger. Here are my subjective opinions as a bowl-latherer, and placing them in order of my favorite to least favorite.
Two-band (fan style): soft on the face, dense, not floppy, has that bit of 'scritch' that is just right, releases soap well, easiest of the three to load (particularly with harder soaps), splay is fine but does not do so as easily as other two (this is a mark in its favor to me). Overall word for it: Ideal.
Silvertip (bulb): very soft, not floppy, pillowy on the face, releases soap well, marginally less dense than the two band. Overall word for it? Plush.
HMW (bulb): not as soft as silvertip, not as dense as two-band, splays the best of the three, marginally the most floppy without being floppy (if that makes sense), delivers soap to the face better than the other two. Overall word for it: Efficient.
Of the three, the two-band was the cheapest when I bought it only sale (~US$12 for two-band, ~$16 for HMW, ~$22 for silvertip—again, all were from the amazing sale of Nov. 11). Pretty much unbeatable performance and value for the price.
