And "cold is better" as a generalization is also pretty accurate in the sense that snow doesn't generally form in large quantities when the temperature drops under about -18 to -20 Celsius. To be clear, it IS still possible for it to snow, but the chances are significantly reduced. The amount of water vapour in the atmosphere at saturation drops quickly as it gets colder than that, so traditional snow becomes less likely as it gets colder. Of course, at temperatures even lower, you can still get a different type of snow from clear skies when dust acts as the catalyst and ice crystals form around the dust.

But the biggest, fluffiest snow tends to fall when it is below -15 and freezing.
