My new formula Tabac arrived this morning and whilst I can't compare to the old one as I have never used it (I avoid Tallow) what I would say is that the performance of the soap is excellent , I face lathered and after a short load from the puck I had lots of very nice lather , applied to the face and then hydrated it produced a rich creamy lather , with plenty of cushion and some serious slickness.
I am not sure if I like or dislike the scent , but there is plenty of that too.
I am a massive fan of Saponificio Varesino and I would say the Tabac Matched it in all of the key areas of Slickness, Cushion , and Richness of Lather. It was maybe not as good in the post shave as S.V.
As always YMMV.
