I want to be able to treat my rifle like a do my lawn mower. Pull it out, gas it up, run it hard for a couple of hours, give it a quick dust off and put it away. Lower end AR's can't really be run like that.
Then don't listen to Bieber.
Buy a complete Daniel Defense, Noveske, BCM, Colt, Spike's, LMT, or whatever and run the crap out of it. If it breaks you now have a warranty-backed gun. If it turns out to not be your "thing", then you can sell it with the better resale value of a factory gun.
As you get more time with it you'll quickly understand how it works and how to maintain it and fix it. Ditto as you start to add accessories.
Later as you hone in what your tastes are in regards to ARs, you can build your next rifles to your own specs.
