Generally I never noticed the difference between SRAM and Shimano, until I tried a PC-1 on a horizontal drop bike. It was garbage, and so was the one I replaced it with, stretched a crazy amount and constantly dropped. Replaced with a KMC on the exact same set up and had no problems at all.
The latest 10spd SRAM I used was OK-ish although bizarrely I had one single roller fail after two months or so, the chain stayed intact but there was no support for the chainring teeth and it sucked badly.
I stopped using them purely because of the price gouging, snaplinks went from 95p for one re-usable link to $4.50 for one non-re-usable* link. I would love to hear SRAM’s justification for that one.
