Yes everyone that was ever issued an AR platform is an expert on the matter.
I voted for Colt, I sold my Colt, and my Stag shoots just as nice for half the money. Noveske and LMT BCM are better, but for the poll I would say Colt, for me, my Stag has been awesome. I don't crawl through mud with mine, or do water bound assaults, so my Stag works just fine for me. I trust my life to it in the conditions I would need to use it, and it always performs great when I take it out to shoot. I got my stag used off here by another member. Used the money from my colt for a different gun, and have been slowly tinkering and replacing parts on the Stag when I get extra time and money.... which is just as much fun as shooting the thing.
An AR is an adult erector set, build your own, so you can't complain that said brand is bad, you put the labor in, you only have yourself to blame.
