i've owned tobs sandlewood, proraso green, co bigelow, tabac, mwf, omega black, speick, williams (obligatory), and cella....i now only own cella in a 1 kg brick that i have been working on for a few months...it is the best soap i have found 100% period....ymmv, and i do believe what your water is like has a profound affect on your soap and lather....where i am at, cella is king.
