I’m tempted to get the Citrus one as my next soap. I had a sample of Fougere a few years ago and while I liked the lather, the scent turned me off, and I had heard then that Original was just a less strong Fougere.
Citrus is lovely, though, nothing spectacular, just very light great scent for summer months. For what it's worth, I don't think Original is just "less strong Fougere" (which same as you, I did not like).
They are not at all the same to my nose. Original is fresh, clean scent, fairly "neutral" and in my opinion, hard to dislike (even if you're not in love with it).
