To be honest I have never seen advertisement from so many houses. I don't think that not advertising says anything at all. It doesn't prove that Creed is better in anyway. The eye of the beholder is where it matters. Ever person has their own tastes and that is where popularity comes in. I think Creed makes fragrances to be wildly popular even though it is still a niche house.
I think the fragrance speaks for itself and Creed just does not make the best smells for me. There are some from Creed in my Top 5 but not enough to make me love is quite as much as so many do.
I like a little bit from a lot of different houses.
I think that all niche houses create unique blends of notes that have strange and amazing qualities to them.
Natural ingredients don't mean anything but natural. Smells are smells. If it is good then who cares if the igredients are natural or synthetic. I want a good fragrance and that is all I care about.
So, to me Creed is overrated by many. I like the house but don't obssess over its few achievements. I have found great stuff from so many houses wether they be designer, niche, natural, old, new, sythetic or whatever. Good is good. I don't feel Creed overdoes good to make perfect scents.
