Having some Nightforce equipped rifles, some sporting Leupold MK4s and now a couple of US Optics SN9s in my fleet, all I can tell you is that each scope has its plus's and minus's. The Nightforce scopes are big, clear and a bit more spendy than the MK4s, a difference in clarity? I doubt the human eye can tell. The difference in available come ups is dependant on the magification level of the scope, in typical design scopes as the Leupold and NF the erector tube is inside the main tube and the higher the maginfication and the thicker the tube , the less adjustment is available. In the HUGE SN9s the adjustments are on the outside of the tube, my new 10x42x58 US Optics has 200 MOA built into the scope, add that to the 45 MOA canted rail and presto I can hold right on out to 2.5 MILES with my 50. The biggest downsides to the US O's is sheer cost $(5500.00) size at nearly 3 feet long and weight at 6 lbs, optically they are incredibly clear, best I have ever seen, but practical, not really.
I would suggest either a MK4 or the NF for 99.9% of the shooting situations 1 is likely ot encounter, mostly for cost effectiveness and size
