I'd imagine after the Shell debacle, that any plastic pipe would be getting a whole lot more scrutiny both internally and externally.

I think the problem with the first wave was the metal sleeves and that the plastic weakened when exposed to some minerals commonly found in water.

It was never available where I live (MA), the codes here are some of the toughest in the country, so no first hand experience. The only question I'd have with the newer generation stuff is how it does in the cold. Winters here can get ridiculous. I've snapped off vehicle armrests by putting my arm on them in a cold snap and ripped off more plastic car door handles than I can remember during cold snaps.
