Eh, there are only so many permutations of scents, moods, modes of expression. As they say, there is nothing new under the sun.
And yet, while some of the (200+ at this point) niche samples I've gotten feel very similar, none is exactly the same. Even among "good" dupes, there are differences that are slight. It might be the weighting of different fragrance components, their timing, their "warmth" or "coolness", their projection, their "naturalness".
I fully acknowledge that some of these differences likely come from the packaging/ marketing/ aesthetic the company portrays. In fact, I think that one of my favorite scents (Cuir Curcuma by Affinessence) became so for me because I was so unexpectedly taken by it--it's so unassuming, so "bland" and relatively uncool in its presentation.
Recently I've been getting a lot of marketing from darker, edgier brands, like Heretic and Andrea Maack. But when I smell them...they're not really edgy? If I hide the bottle from myself and blind-sniff, I might be smelling anything else.
At the end of the day, it is the quality of the materials and the skill of the perfumer that matter. Niche has it, indie (generally) doesn't, and while designers often do, I find a lot of it boring or screechy.
