I just got back from a weekend guiding aoudad hunters (2 this time). As usual I got to inspect their equipment, and test out my VX6 and my buddy's VX3 4.5-14 non AO (7 STW). To make a long story short, at lunchtime we ranged and shot 2 ft sized rocks. I could consistently hit @ 600 (4 for 4), 740 (3 for 4), and 908 (2 for 3) with my VX6, 7mag, shooting HSM trophy gold 168gr VLD hunting bullets. Not 'cause I'm a great shot, but because the MOA dial on the VX6 tracks perfectly, up and down and back to the 100 yd zero it started with. We had about the same consistency with my buddy's 7STW, and another hunters Nightforce 5-22x50. It obviously has the SF adjustment. The glass in my VX6 was noticeably better to my 51 yr old eyes than the NF. My conclusion was that I personally have no need for AO or SF. I could hit those targets on 6x-12x rather easily. No wind of course.
