About 15 years ago I installed a new kitchen faucet for my grandmother, whose kitchen had been renovated in the early/mid 90s. Right near the end of the time when PB was inexplicably popular. I have to say, I spent several hours cursing whoever decided to use PB, and in this particular case whoever decided that the pipes should connect directly to the faucet rather than terminate at a bog standard quarter turn valve. Lots and lots of cursing.

As I recall, wasn't PB basically a single vendor, too? Finding PB-to-anything-else adapters at Home Depot was like going on a treasure hunt. Sizing is different, so you really need something actually built for PB. And probably end up with sharkbites. If I were shopping for a house right now and found it had been plumbed with PB, I'd just turn around and walk away.
