Lately I've been getting the urge to try a synthetic. Currently I own just 2 brushes, both Simpson's Best Badger, a Duke 3 and a Commodore 2. I mostly face lather with hard soaps (MdC, Stirling, Mikes Natural, Speick stick). Among the models I'm considering are the Yaqui Moka Express, Yaqi 24mm Sagrada Familia and the RazoRock Hive 24. All are under $20, and with zero experience I don't have a clue which would serve me better, or if there's another synthetic I should be looking at instead of the above 3. Price matters, but if there's one that is absolutely hands down superior, but is more costly, then by all means tell me about it.
