I have rifles with both and don't really care for the red dot. They are great for action pistol shooting, but IMO they don't amount to much on a rifle. Steve makes some good points. I also think that accurate aimed fire if tough with a red dot. The dot gets real big, real fast. I have the Leupold LG/35 with the smallest dot, but the dot still covers a lot of area. I also seem to have parallax with my red dot; if I don't have my face in exactly the same place against the stock, the rifle doesn't shoot in the same place, and it seems critical. For example, sighting in off the bench vs. shooting off hand. On the other hand, I like the scout scope a lot. I mounted a Leupold Scout Scope on a Marlin 444s and mounted one on a Finnish M39. Both shoot much better with the scope than with the iron sights. They are fast, and utilize the available light better than iron sights.
