I’m by no means an advanced shooter, but one of the things I really like about both brightly colored front sights and red dots is that I can still get good hits (passing the Test by either Vickers or Hackathorn scoring standards) with a target focus. It’s much easier to maintain a hard target focus instead of a soft focus with the red dot, but either way you start breaking the shot as the brightly colored thingy starts falling back into the acceptable target area.
