Perhaps the most boldly ignorant statement I've seen posted here in a very long time. Quality boar and badger brushes both get the job done in terms of building and applying lather. What has face feel got to do with lathering viability? Your statement is similar to saying a synthetic paint brush cannot take the place of one made with natural bristles. If they can both paint a board, then one can take the place of the other plain and simple.
Argue the merits of boar or badger over the other all you want. Ultimately, the fact remains either type works.
What other wet shaving wisdom have you been withholding from us for the past 5 years? :rolleyes:
