There are so many choices out there. I like in this order; 1} VDH Deluxe 2} VDH Luxury 3} VDH & Williams For the price you can not beat Van Der Hagen Shaving Soaps or Williams Shaving Soaps. I basically use Van Der Hagen Shaving Soap every day.
Mitchell's Wool Fat and Arko. I plan on giving the Cella go here within the next few weeks (or months ) and hopefully that'll be one as well. I used Williams for years and years, and while I don't think it performs on the same level as the MWF or the Arko, I'm sure I could manage with it alone again if I had to. No worries at all really.
I'm a cream guy but use soaps occasionally. I think I could probably use a croap type like Proraso or Razorock everyday.
The only soap I have used is Van der Hagen Deluxe. If I had to use it exclusively it would be sufficient. Glad I've got more choices.
