I personally use BJs gas, the one closest to me has always been good, or even better than some top tier stations. When I've run data on this and past cars, I almost never see corrections from knock, whereas a couple of the top tier stations I would see more. I have heard of people having issues with their gas in other regions though, so I'm sure it varies quite a bit.
