The March is about the best hunting scope I've used. It has great glass, low profile turrets, 25 MOA per rev, 120 MOA elevation, light weight, probably the easiest zero stop to set, and a 10x magnification. The 42mm will lose light at 25x, there's no way around that small objective up front at that power. Not a lot of 42mm scopes go to 25x for a reason. I haven't gotten the chance to test it against my ATACR but it beats the NSX glass at 15x, as well as VX-6(3-18x), XRTII(5-25x), and SIII96-24x) but is in a different price bracket than those. I would suspect the 56mm front on the NF would win.
I have not compared it to my VX-6 4-24x52 yet but that will be a fairly even comparison but the VX-6 only has~70 MOA.
edit; I usually don't turn scopes up to 25x when shooting but do use it to see details, mirage etc.
