I posted this reply in the last cologne thread here:
Acqua di Gio is not "by far the best", it's only by far the best marketed. Most girls will say that's one of their favorites because it's one of the few they like that they smell all over the place. Doesn't mean you can find one that smells better and smells original. That's what you want to look for. While it's not exactly an obscure cologne, I usually wear Swiss Army. Girls love the hell out of that stuff. I also have Cerutti Image and Insurrection.
Plus, if you wear a nice cologne that is rather obscure, for the most part girls will associate that scent with you and will have to be around you to smell it. That's another incentive to stay away from the really popular stuff.
And I tried on Angel a month or two ago. It's a really interesting smell and I liked it....smells kinda like cocoa and chocolate...but supposedly while some people love it, others hate it. And I don't think I'd want to wear something that a lot of people around me will probably hate.
