In my experience, it became very obvious very quickly the superiority of the Richeson brush. I think they must do something to the tips of the brush bristles that makes them smoother, as all other brushes I've used have been more coarse which leads to anywhere from very mild to very obvious surface abrasion. Other brushes tended to absorb more emulsion into the bristles while coating, thus requiring more emulsion to cover a given size print. Yes, they're silly expensive, and the ferrules and handles are actually quite cheaply made, but the bristles are something else entirely and make it worth the price.
