I think that my favorite artisans; B and M, Saponificio Varesino, MDC and a few others offer more protection during the shave than what I got out of either of these. I will occasionally get a little feedback from the alum with them and it's usually localized to a small area. My entire face lit up when I used the alum, that hasn't happened in quite a while. Now, to be fair, I'm at the end of this blades use. When I compare the Dr Jon's to the MDC if I don't get any burn from the Dr Jon's I'll revisit it and blame the blade.
