To me they are not the same. I liked D600 way more, but I think I'll be in the minority on this one. D600 has Dior Homme qaulity to it minus leather and add pepper to it. As weird as this sounds Bois D'argent reminds me of a barn yard. Not a dirty barn yard, for the life of me I can't figure out why I get this vibe from it but I do.
