However, plastic pipe of any kind is not very good at resisting physical

I'll gladly hit PEX with a hammer and it won't affect it unless I try
to crush it entirely. Lesser blows would destroy any other piping,
metal or plastic, before the PEX showed lasting damage.

PEX has a plastic memory - it returns to shape. No other plumbing
material that I'm aware of has that. It's what makes it so much more
freeze-proof than other piping.
