Far from Junk. I own three T6xi’s. They got them right. The only problem if it bothers some they have is a soft (not easy) turret feel, same as Trijicons I own.
OP, all of them listed are good optics. I would say the PST ii is towards the bottom far as reliability, and the nx8 has a tight eye box I didn’t like. The rest of them just weight out your options of what you like and want from it by size, weight, turret style and mechanics, glass, fov, reticles, etc…. Pick the one that fits your criteria the most and go with it.
