In my own experience I've come more to believe it's more the mount used, style not brand, and tuning the rifles gas so that it's not beating itself to death.
I still like great glass but that's my theory. I have a NXS in a UTG $60 one piece mount that's going on 500 rounds no issues on one of my 17S......that's been my experiment.
