YMMV. I ran Snow Leopard on a couple of machines for years—bought it off CraigsList for $10, handed off in Times Square—and it was far and away the best OSX experience I had, and, at least in my experience, the best/smoothest/most stable until El Capitan, 10.11. And yes, maybe I'm thinking of 10.6.8, but I don't see why that's a problem.
The myth part, is of course, a myth, and good marketing. Snow Leopard was super important for the OS, changing a ton: <https://en.wikipedia.org/wiki/Mac_OS_X_Snow_Leopard#New_or_c...>. Marketing gonna market.
Regardless, I can agree with this:
>People invoke its memory because they’re broadly craving stability and quality of life improvements, something almost everyone has wilfully discarded as they chase the next rung of enshittification.
