People seem to forget that there are several March scopes. There was a thread or two a while back where most allowed that the fixed power 50X was a disappointment, whereas the variable 10-60X was a treat.
I have a Nightforce 12-42 BR that is not real clear. People who've looked through it allow it's disappointing, and probably not typical. For that reason, I like the optics of my Sightron III 10-50X 60 better. Price wasn't 1/2 the NF, though. The cheapest I could find a Sightron was about $850, and a new NF-BR 12x42 is more like $1,425.
I find the side focus of the Sightron terrible, apparently the quality of that adjustment varies across individual scopes. A larger wheel might help.
Don't know if we've collected enough data on the durability or any POI shifts with the Sightron so far... But I put one on a .22 RF, and could easily quarter the x-dot on a 50-yard rimfire BR target, indoors! Pretty darn good.
