The problem of the 4.5-14X LR scopes is that, due to their side focus/parallax adjustment, they have a much shorter depth of focus. Since big game animals tend to show up at ranges that can't be planned in advance and sometimes don't give you plenty of time to fiddle with your scope's various adjustments, simplier is better.
Properly focused, there is no significant difference in image clairty between the VX3 w/o an AO and the LR version. Properly focused meaning focusing the reticle and the image using the scope's ocular. E
