I just did a quick comparison among Obsession, Tiffany, and Must de Cartier. *I had a hard time of it because my SOTD is Gucci Nobile and that scent may have intefered with with my test. *First, cross out Must--I think it's a completely different fragrance. *I does seem to rely on a smooth musky delivery which is very different from Obsession's. *Smoothness doesn't seem to be a part of Obsession's intent, also, the notes are quite different--Obsession heads toward green and Must goes toard spice. *Obsession has a heavy reliance on corriander and pine where Must seems to have nothing that interesting. *
There's a little similarity between Obsession and Tiffiny, primarily in the commonality of rosewood and patchouli and amber. Also the tonka of Tiffany partially makes up for its lack of vanilla. *I do catch the rosewood/patchouli similarity, but that's where the similarity ends IMO. *The impact of the two is totally different. *Tiffany is definitely a solid wood Oriental very masculine and concrete. *Obsession lacks the sandalwood so its power goes in a completely different direction--more abstract. *Obsession is quirky, Tiffany isn't, and Must is so straight it's quite boring IMO. *
I'm not good at comparisons between fragrances, so keep that in mind: *I really haven't come across anything quite like Obsession. *It's as unusual as Opium but in a smoother and darker and sneakier way and Opium has had its imitators--Obsession hasn't to my knowledge. * Milamber says its message is because of the tension between its gormand notes and its green/pine and I think he's absolutely right. * Obsession glorifies in its tension.
As far as being masculine--I think it is, but if you are wearing Egoiste and Tiffany and English Leather, Obsession for men certainly won't be a problem for you.
