Old plumbers don’t like that pex stuff much. It looks like cshit no matter how you install it.
I know of a successful plumber in NJ that did the copper on my parents new home back in 1963. He related a story about getting a service call of pipe leakage a few years back and the 40 year old copper pipes were so worn out that they could be crushed by hand pressure. I would not even think of having a home not built with Pex tubing in it.
