I don't think it's a niche vs designer thing. In fact, I think that's a copout. Lots of designer scents get plenty of love here on basenotes.
Gucci Pour Homme II is a designer scent and shows up on so many best of lists here.
YSL l'homme and La Nuit are as designer as designer gets and they both get lots of love here.
Dior Homme. Lots of love and available at the mall.
Mugler Cologne. Again, loved here and available at the mall.
Chanel Platinum Egoiste, AHS, and especially AHS Edition Blanche.
Burberry London gets no lack of respect here and can sometimes even be found at Ross!
FAHRNEHEIT! I don't see anybody hating on Fahrenheit because it's a designer scent.
The thing you have to do is accept that your opinion can be different from others and that's A-OK. You love 1 Million. Wear it and enjoy it.
