Google up Wirsbo and check out their "WRITTEN" 25 year warranty on AquaPex.
Ever try and get a copper pipe or fitting mfg., to cover a defective piece?
Forget about it.

If you are indeed an old fart, 25 years is long enough.

Well, (1) it took 30 years for the copper tubes in my concrete slab to
rot out. (2) Will AquaPex be around in 25.1 years? (3) will they
have assets so you can sue?

FWIW, I went through this decision in 2001 and came up with "Use Copper"
and chop slots in the slab to get passed doors.

And, check national, state and local building codes to see if PEX is
permitted for fresh water. If you're doing heating lines, you will
also want to do fresh water at the same time.
