Si vs Mon Guerlain

The community has mixed feelings about Si Intense, with significant division centered on reformulation issues. While those who own original versions love the blackcurrant and fresh qualities, many are disappointed by recent 2021-2023 reformulations that have weakened performance and changed the scent profile. The newer versions are frequently criticized as generic and underwhelming compared to the beloved original black bottle.

The r/fragrance community views Mon Guerlain positively overall, praising its comforting vanilla scent and broad appeal. However, some users experience disappointing longevity and projection, and it's often dismissed as an overly safe, mainstream fragrance rather than something distinctive. Many consider it a good blind buy at discounted prices.
