For what each was/is intended to do, I believe that Vetiver de Puig is the better fragrance. This was developed as a true masculine eau de cologne; vetiver presented in a clean, refreshing, barbershop context, available in a splash format, which is what I have. I also have the L'Occitane, which if you know L'Occitane at all, is intended to be a mid-tier sporty luxury unisex fragrance. While a good overall effort, it is awash in a sea of similarly intended vetiver fragrances.
Vetiver de Puig was and continues to be more unique in its context than the L'Occitane, and for that reason it gets my vote.
