I have used both DR Harris and Arko soap. I have always noticed I got a better shave with DR Harris and found I get a get a closer shave with it as well. Yesterday , I did a side by side test on my face and I could not believe the difference on how mu ch the DR Harris out performed the Arko for me. Has anyone else noticed a big difference in performance between these two soaps? Arko has good glide , but I am thinking DR Harris also has better cushion for the razor.
