What's your purpose for the rifle? That will driving which to pick as much as anything else.
Personally, I like the Colts. I have a 6920 and a really want an AR-15A4 at some point. Most stock, single-stage mil-spec triggers are rough. It's what they are. I'm not a trigger snob so I find I can get along with them just fine unless it's for true target shooting.
Regarding the 20" vs 16" guns: with a proper Government profile barrel, the 20" guns aren't actually heavy. Avoid at all costs anything in a heavy barrel or H-BAR that is thicker under the hand guards. And the .223 really thrives on velocity, anything you can do to keep the bullet speed up is a Good Thing.
Now the A2 length buttstock the Marines foisted off on everyone makes the AR a better target rifle, but is a bit too long for most other uses. Given my way, the fixed length buttstocks would be the original A1 length, which is about 3/8" shorter. This is handier and easier for most people to use.
Chrome-lining may or may not affect accuracy, depending on whose barrels you're using. Colt actually has a pretty decent reputation for the accuracy of their chrome-lined barrels. I knew many Highpower shooters who would use chrome-lined barrels to start on rattle battle and loaner guns. (They'd replace them later with match barrels as they wore out.)
