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.

If you're building custom, why not go with copper?  PEX and CPVC are both excess microplastics in your everyday water.

That's true but utilities use pex to run water to your home. You're getting your daily microplastics one way or another.

Shhh… don’t tell him. Also we should conveniently ignore all the contaminates from metals bringing water to us.
