I switched to tallow early last year (2018) because I can very strongly smell the "pig factor" in soap, although none of my customers seemed to notice. The soap is a bit more cleansing, but soap itself is harder and the bars last a bit longer, lather seems to be very comparable. And I don't notice an animal smell to it.
Lol, I'm just the opposite; I can detect a little animal scent to Tallow but not Lard. Funny how we all can detect different things. Happily, the scent is non-detectable in the finished products of soaps made with either Tallow or Lard.
