Like many I have travelled thru many synthetic brushes to find a sweet spot that works for me. Face feel is the most difficult element of a brushes characteristic to describe and you will have your own preferences. If you like a cloudy, soft, smooth, pillowy face feel, the Yaqi brushes will probably suit if you can get one that does not have a large glue bump, but for a little bit more (at least in the UK) Simpson's "Trafalgar" synthetic brushes are better quality and perform better. However my experience with synthetics is that the hand tied knots from Muhle (STF) and Simpson (Platinum fibres) are something else and worth every penny. With Simpson's Chubby synthetic you want to aim for a loft of 54mm if you want the knot to splay readilly; a shorter loft will give you a ton of backbone - no other synthetic brush comes close to the unique feel a CH2S gives. Muhle's 19mm STF is for me the pick of the bunch in Muhle STF range, if you are a face latherer. It feels sparse, small and quite scrubby at first, but the more you use it the more you realise it is something special especially if you have tried other synthetics. it's size is not an issue in use. Their other knot sizes are nothing special except the discontinued 25mm which was good, but Muhle's 19mm STF is the dogs danglies. Both Muhle and Simpson are hand tied knots, set deep in the handle with no glue bump above the handle socket opening. This method of construction affords these brushes superb progressive splay and great flow thru. Both these brushes have prescence at the tips or a for want of a better description some scrub and not the cloudy, pillowy softness of many other synthetic brushes that effectifely use fibres developed for makeup brushes. Omega's EVO is also a superb synthetic, the construction of the fibres allows the knot to hold water and the water retntion and face feel is the closest any manaufacturer has come to how a badger feels. Large glue bumps have been a problem on some of their brushes though. Muhle, Omega and Simpson are the only brush manufactuers who had fibres developed / tailored for their synthetic shaving brushes - it shows
