I'd take Allure Homme over Allure Homme Sport, but there are quite similar.
Both can be sampled at department stores such as Macy's.
Some Bloomingdale's stores stock Antaeus. Platinum Egoiste is a bit less
commonly stocked than Allure Homme, but still not hard to find.
I think Chanel's are top quality, but I don't think they are exceptionally
long lasting. They last long enough, but not as long as some others.
Platinum Egoiste lasts the longest of the Chanels and Pour Monsieur (1955)
lasts the shortest. I think Pour Monsieur is the best of them, though, and
Platinum, while good, is about my least favorite. Understand, though, that
even their "worst" is better than most of the department store scents I
see in the sample trays these days.
My opinion, of course.
Start by sampling Allure Homme.
