I got away from the ARs a long time ago, and got into FALs, which I think is one of the finest rifles ever made. So, coming back to ARs for something in .223, I followed along here for awhile before deciding for myself. After a lot of reading, and handling Colt, BM, etc. I decided that I prefer Colt, if I can afford and get them. I first traded a Robinson M-96 recon for a BM Dissy, just to get rid of that pathetic attempt of a gun from Robinson...don't get me started on that POS. Anyway got back into with with a bushie, and it's pretty good. Then I picked up a couple of Colt uppers, and have been very happy with the quality. I put one on an LCW (LMT) lower with colt internals, and just ordered a LEO lower for the other colt upper. I think it's the little things I like best about colt. Parked under the FSB, MPd bolts, etc. I don't put much stock into what gun magazines and writers say...mostly full of it. I do however respect what Pat Rodgers has to say. He's a been there, done that, kind of guy, that is exposed to a lot of weapons over extended periods of time. And unlike someone like Massad Yahoob, he has actually met a gun he doesn't like. Meaning, I think he's straight up with his info. Check out Pat on Tactical Forums.com, great guy who knows what he's talking about.
Bottom line...he names Colt as the only tier one AR, and the rest are 2nd or 3rd tier. Doesn't mean I wouldn't want one of them, but if I want what I think is the best, I get a colt. Although I think the company leaves a lot to be desired because they don't really cater to us lowley civilians, doesn't mean that they don't make a fine weapon. Just to be clear, I went into my quest for an AR trying to justify not getting a colt.
