Don't want the fittings to burst in freeze.
Also while PEX can survive being frozen, I have not seen much about total number of cycles it might sustain before weakening.
Edit: Also I want to be able to drink water in winter.

At this point, I'd probably go for PEX-A (compression band) over PEX-B (the crimp style) because of the risk of getting the crimp not completely correct.
