I've sampled both fragrances at different times. I don't recall a similar vibe. Now with Canali Summer Night, it did dry down similar to the original Canali Man. I suppose Summer Night basically added some refreshing top notes to the mix, kinda like how Eternity Summer from Calvin Klein starts to smell like original Eternity once it starts to dry down. I do remember the first time I smelled Aventus, I thought I did get a leather smell, and Canali gives me leather as well. So, maybe the leather vibe was what Franchizzy1 was referring to. A lot of people are gonna try to make Aventus, or any other Creed, out to be some house where you can basically find a much cheaper substitute. Now maybe with Original Santal, you could easily argue Mont Blanc Individuel or even the whole Cool Water/GIT thing. Aventus is still pretty new. Maybe sometime soon a similar designer clone will hit the shelves, but I don't think its really happened yet.
