What is the best Man Scent (Perfume)... Only woman opinions please:)

there has only been on cologne that a guy has worn that i thought smelled fantastic. and that is Eternity. i THINK its made by calvin klein..not sure though. whenever my ex wore that stuff it was great, i could sit there with my head on his shoulders just smelling his neck forever lol! which of course usually led to other things! however..i have smelled Eternity on 2 other men and i guess it just didnt mix well with their body chemistry, cause it did NOT smell the same. not necessarily bad smelling, but definatly not as great as it did on the first guy!
