I haven't used the Cepex, but these seem to be pretty high quality. Far better than the hardware store ones, but I've only had them installed for a couple months. Others that have had them for years could probably chime in.
They are the same as the ones sold at Marine Depot with good reviews.

Is there a difference in quality between Cepex and other true union ball valves at supply house.com?
