Polyurethane bushing squeak
It really comes down to a personal choice. Can you stand a little extra road noise and vibration? Then great, run poly or delrin. Want it to handle like stock? Fine, use rubber. No need to throw third grader insults at each other for the other's choice. People have run poly bushings for DECADES on Mopars and you don't see problems on a large scale. So, that means either one of two things. Either incorrect installation, or defective parts. Take your pick, but all this childish nonsense with all the name calling adds to none of these discussions. It really needs to stop.
In the end, just run whatever bushings you want to run.
