Use parking brake during winter, or not?

[Vronsky]

Fella's,
I'm not sure whether to use my parking brake during the winter, or not.
Using the parking brake when it freezes can warp the rotors, and damage the pads. The downside of not using the parking brake, and simply parking it with the gear lever in P position (auto) is that the auto gearbox can get damaged when it gets hit in front or rear by another, parking car.

Any advice?
