A huge disadvantage with PEX is that it is semi-transparent. If your water supply has nutrients in it and the PEX is installed so that light will get to it, you will find that algae (green), bacteria (black, orange or yellow) will grow inside it. It sloughs off in long, stringy goop similar to the biofilm that grows in diesel tanks that haven't been treated to prevent bacteria growth. Keep it well hidden in walls and away from crawlspace vents where sunlight can penetrate.

Keep squirrels away from it, they find it delectable.
Also another advantage listed is that there's no lead. That's true insofar as you stay away from the type that requires brass fittings.
Otherwise, you have a highly flexible, smooth bore water supply system that will allow for using smaller tubing, which can speed up hot water temperature delivery. It's cheap enough that you can do end-run (star) delivery to a central control manifold, typically each run will only have two joints, one at the manifold and one at the the coupling to the shutoff valve. You also don't have a problem with meth addicted copper thieves coming and stripping your house plumbing out if you leave it unattended (summer cottages, another reason iron ain't so bad).
