I haven't used either of these soaps, but which one do you prefer? Which one lathers better and smells better? Also, is cella a shaving soap or shaving cream?
Get both of them.
Both are classical , legendary soaps in traditional shaving world.
For me Cella is better performer during shaving. Slickness, moisturizing and protection is better than Mwf.
Mwf has all characteristics of a British soap. Post shave feeling is great.
If i have to choose one, it would be Cella.
