I think
@greeneyes summed it up pretty well. However, we all imprint on the blends as they are when we first smoke them and judge them on their merits. So someone may like a current iteration of a blend because they aren't familiar with earlier versions, like I am with Escudo, where I think the current version is a mediocre version because I imprinted on the earlier Copes and A & C Petersen versions. And it isn't a matter of aging. Aging isn't a guarantee of anything except change and that change isn't always beneficial. Nor is it a matter of nostalgia. I'm not the nostalgic type unless it's Helms Bakery trucks.
And the blends I smoked 40 or 50 years ago might have been someone else's idea of crap compared to what they smoked 70 years ago.
All that said, blends that I became familiar in the recent past, 6 to 8 years ago, have changed in ways that I don't experience as improvements, Director's Cut, Makhuwa, and Motzek Strang being three examples. The 2020 release of Dunbar is another. I wouldn't spend a nickel on another Esoterica blend.
It is what it is for me. For new smokers, things may be just fine as they are.
With current releases, Watch City blends, the Sutliff produced Seattle Pipe Club blends, and some of the limited boutique blends that KBV releases are blends that I enjoy.
I'm glad that I bought what I did when I did.
