Polybutylene QEST "Quest" pipes in my home

I don't recall any class action suits against copper

So, I see this is an old forum. Any option for the stop valves under sinks and toilets with Quest Poly pipe? I have had no issues with my pipe, however, the plastic valves seem to blow without warning. I have replace them all once, I’m getting ready to replace them again, just to be safe. Can I replace the quest valve with some kind of metal? They are all 1/2” quest out of the wall and then 3/8” to the sink or toilet.
