Early versions of Snow Leopard did have a bug that could delete all the data on your hard drive. :)
10.6.8 was pretty good, but I've had similar stability on Mountain Lion (10.8) and Mavericks (10.9). I think Snow Leopard has developed a legacy partly because Lion (10.7) was pretty bad, and partly because Snow Leopard was the last release to support Rosetta.
Then again, Yosemite (10.10) was also really bad, and I seem to be the only one who thinks Mavericks was the actual pinnacle. *Shrug*
