Aramis and Quorum both smell distinctively like old man to me.
Old Spice may be the most classic old school fragrance, but because of the popularity of their body wash and deodorant lines, everyone is familiar with the Old Spice smell and plenty of high school kids even smell like it. It's not distinctively old man enough anymore thanks to good marketing.
On the other hand, most high school or college kids wouldn't be caught dead smelling like Aramis or Quorum. They aren't bad smells, but they smells very much like an older gentleman from another era, and they're both STRONG stuff that people will notice.
