PVC shatters when stressed - say, by having a heavy object drop on it
(a.k.a. "catastrophic failure", a.k.a. "your entire water supply in your
bilge".) Hose doesn't shatter - but it can be punctured or cut
relatively easily. PEX has the advantages of both (i.e., it is both
flexible like hose and allows you to use elbows, etc., like PVC) while
not having the disadvantages of either (won't shatter, very hard to
damage accidentally.)
Now that PEX is available at the average hardware store, I can't see any
reason to ever use anything else on a boat. Manufacturers should have
been doing it for the past 20 years.
