Yeah, I personally remember "10.6.0 utterly fucking sucks" (though it got better) — hard to remember the details, which is probably in my personal best interest, but I remember fairly vividly shouting that to friends over beers somewhere.
And I also remember 10.7 actually being better and where I thought Mac OS X (and its macOS rebrand) peaked, for interactive/workstation use.
However I ran a 10.6.x virtual machine (that yes, ran Mac OS X 10.6.8 Update Combo v1.1[1] for the last decade of its service life) until 2021 for a bunch of long-timeline server functions, so I guess Snow Leopard was pretty good overall, in the end...
