I see most Aimpoint (esp T1s) dots as a 12 moa pixilated stripe. BAD. I find the EOTech dot better, still pixilated pretty good but more or less round . . . errr star shaped I guess.
I've seen some crazy good offhand shooting on a chest sized steel plate at 200 yards by Frank Proctor with an EOT. I'm guessing his vision is pretty tight though.
