So often, frags are simplified in discussion to a single note. It seems particularly true for these two. Both are more complex than many would suggest. Further, they don't really smell just like chocolate and licorice. If they do to you, your nose needs more practice. Just hoping this thread doesn't go the way of chocolate vs. licorice. We're better than that- evidenced by the "conspicuous woody base" comment mentioned above. (formerly Vibert?)
Having said that, the sharper notes in Rochas Man are not as harmoniously blended as I would like. The cedar, floral (lily or jasmine) and citrus are interesting and bring a certain hip feel to an otherwise basic gourmand. However, for my nose, the blend is confusing. It feels more like two separate frags poured together.
The Au Masculin is a smoother blend with better consistency throughout. The journey includes a sharper note or two but maintains a warmer, smoother, yet still unique and contemporary concept.
Often these decisions come down to a personal preference for one note over another. The more notes in common, the more objective the comments are likely to be. Frankly, I like both Rochas Man and Au Masculin. I can see how they would spark comparison.
I enjoy the Au Masculin experience more than the Rochas Man. Au Masculin feels more unique and better blended IMHO.
