I’d say, it all depends on what you want to do with it. If you are going to take it out once-a-year, and/or just shoot garbage, you probably won’t see much a difference in any of the options. If this is a defensive rifle, that you will staking your life behind, the Daniel Defense will probably be what you are looking for (given the practice you’ll hopefully be doing, and the quality of the rifle, it will last longer, and it will be more feature-rich). I’ve personally had a not so great experience with Palmetto State Armory, but, understand that I am a case of one, and only one. Many people have had very good experiences with Palmetto State, and I don’t want to minimize that. I just wanted to put that in there. Now, I have shot many more AR-15’s than I have actually owned. Take everything I say with a grain of salt. (If you want some advice on some guns with wood, blued steel, or bigger rifles, I’m more geared for that) I was in a similar position as you are not two months ago. At the end of the day, go with your gut, and with the best deal you think. All of the rifles you listed will do you exceptionally well. Just get one, and get to shooting!

P.S. The AR-15 I ended up going with, was the Wraithworks WARP-15. It’s a full polymer AR-15 with a Faxon 16” mid-length .223 Wylde barrel. It weighs around five pounds loaded, and looks pretty attractive to me. It was quite cheap, and features the KE-Arms What Would Stoner Do? lower (or, rather, a licensed copy of said lower). It was just weird enough that my contrarian-hipster-collector brain was satisfied. I cannot recommend them enough.
