Stirling lathers incredibly well face or bowl lathering.
I believe you will find them very similar. I can't imagine how you would design a soap for bowl lathering over face lathering. I'm not certain, but that sounds a lot like the stuff that comes out of the back end of a bull.
I don't know about CRSW, but I do face lather with Stirling as well. I am new and still struggle a bit with face lathering. One thing I have noticed and read... Stirling is fairly thirsty. You will likely have to add more water as you are lathering. I really like Stirling. It is a slick soap with excellent scents.
I face lather exclusively and my Stirling Barbershop performs as well as any of my other soaps. Good stuff! Highly recommended
