I will vote for none of those that you listed.
A good out-of-the-box rifle is the Stag 3G. It comes with a 1-in-8 twist 18" stainless steel Shaw fluted barrel, a Samson Evolution free floating handguard, a Stag 3G compensator, rifle length gas system, Magpul ACS stock, and a Geissele S3G (super 3-gun) trigger. All for around $1400.
You will not find a better gun for that price, and while they are hard to find and you might have to wait a month or two.....it will be leaps and bounds above any of those other guns that you have asked about.
