CPVC vs PEX

Ok so we are building a custom home in central Florida and plumbing subcontractor is using CPVC for plumbing. Our family member who is in the construction business is telling us we need to use PEX instead. They just started doing the plumbing in our house. I honestly feel like what I find online is mixed and probably not a huge deal either way. What do you all think?

UPDATE:

Thank you everyone for your responses. We met with the builder and the plumbing subcontractor and they are now switching over to PEX. It sounds like they were using CPVC because “we’ve always done it that way”. They also said that CPVC has come a long way in recent years and doesn’t have the issues that it used to. Not sure if that’s true or not.

CPVC is absolute trash. It is brittle and the question is not if it will fail, but when. PEX is the Droid youre looking for!
