As I recall, there were plenty of legitimate user gripes when the very first iteration of Snow Leopard (10.6.0) was released. But by the time of the very last point-release (10.6.11?), the OS was rock-solid. It was only after all the initial bugs were ironed out, that Snow Leopard achieved the legendary status that it has enjoyed ever since. The blogger doesn’t take this factor into account.
Mavericks played out similarly as far as I can recall. Earlier releases had issues but by the last minor update it was quite solid.
10.9 my personal “Snow Leopard”. It has most of what made the Aqua era releases good with some QoL/polish improvements. If I could patch it with non-flat scrollbars and 10.5/10.6 2D grid spaces it’d be perfect.
It was 10.6.8 v1.1. They didn’t want to increment the version number so they made a version number on top of a version number.
