I have two NSX compacts and have shot alongside NF BR scopes in F Class.
The difference between the two are as a you say robustness, plus a few other features that favour hunters and military types, as opposed to target shooters civilians.
The focus/parallax adjustment on the BR is at the objective end of the scope. This means you have to get up out of a prone and reach forward over the rifle to focus it while looking though the ocular. The NSX and Competition scopes have a side-focus which is a lot easier as you do not have to break your shooting position.
The BR has removable turret caps in order to access the windage and elevation knobs. You need to keep these from getting lost once they come off. The NSX and Competition has waterproofed exposed turrets.
The BR and Competition advertises a coiled spring to improve tracking. It's the little knob/housing that protrudes at 45degrees offset to the windage and elevation knobs in the centre bulb of the scope. This is designed to improve repeatability by supplying more tension to the movable windage/elevation mechanism than normal leaf springs. This was originally an after-market idea to improve repeatability in Leupold Mk3 scopes and NF has taken this on board in their factory design. The NSX uses titanium leaf springs and I have never had any issues with tracking/repeatability..
Lastly, the 12-42 BR (I think '42' is what you meant) does not have a very generous elevation range. It only has 40MOA of total travel. NF sets the reticle at the optical middle of travel so you only have 20MOA up and 20 down. If you want to shoot at 1,000 in Grendel you will need at least 43MOA of elevation travel above a 100yd zero. The NF Competition series has slightly more travel; 45 and 55MOA. You don't want to be messing around with shims and I take it you will want to zero at 100yds. Some competition shooters zero at 300 to save a little elevation here.
