They’re nice rifles. Like someone else mentioned, all pretty much the same.
I own a S&W M&P 15 223 (OR), and love it. Threw some Troy battle sights and an Eotech on it, and it shot so well, don’t really need to practice with it.
Handguns, on the other hand...
I also have the S&W M&P AR-15 and a $500 EOtech on it. It’s a good AR. I will not shoot Wolf ammo because Delton’s AR 15 comes with a flyer stating their warranty is void if you shoot Wolf ammo in it.
Just my 2 cents ... your opinion may vary.
