PEX is spectacular. Easily the best plumbing system. It's dead easy to install, it doesn't require heat, it's very fast to install lowering labour costs, the pipes have lower friction so you can generally go down one size and get the same pressure loss, it's flexible so it can go around turns, it's water hammer tolerant, it's freeze tolerant, it's not conductive and doesn't corrode, and it doesn't care if you have acidic ground water. Plus probably a bunch of other stuff that I'm forgetting. It blows the doors off of copper by every single measure, other than rats and mice can gnaw on it.

PVC is terrible, but plumbers love it because it makes straight lines. I had a plumber argue with me when I was doing over my house about installing PEX, over a job he wasn't even doing.
