I’ve lately taken to face lathering and find my Simpsons Duke 1 in Best Badger to be superb for this. Not wanting to leave well enough alone I ordered a Duke 1 with Sovereign Fiber and cannot believe how dissatisfied I am with this synthetic. I don’t know if it is the grade of fiber but it doesn’t feel like half the brush the badger is. I was hoping for them to be more similar but, nope, not even close. I have the Duke 3 with platinum synthetic, which I really like, and it is my go to brush for bowl lathering.
