Yes, the version of Snow Leopard people are referring to (and have fond memories of, me included) was 10.6.8.x. The point is really that it was given time to mature. (Back in the day, users used to explicitly refer to "10.8.6", and not just globally to "Snow Leopard". Similar to how people used to refer to 7.5.5 and 7.6.2 specifically.)
