As David mentioned, the most common scope at a big F-Class meet is the NF 12-42x56mm. When spending my own money for strictly my own use, I go for the BR series. The 1/8 clicks are nice, but IMO not strictly necessary - 99% of the time I'm holding off somewhere in the scoring rings anyway. The front adjustable objective is easier for me to eliminate parallax with as you are making roughly the same adjustment over a larger rotation, so you get a little finer control.
The biggest 'advantage' of the NXS for me, is that the mental math is easier. ~3 revolutions @ 10 moa ea to 1k, vs. 5 @ 6 moa each. Since I normally grab a fist-full of windage,either moa or revolutions) and then hold off inside the X/10/9 ring, the size of the clicks doesn't matter a whole lot to me. With 10 moa per revolution, it used to be a lot easier to not get 'lost' as to which revolution I was on with a NXS than a BR... but with the new 0-5-0 windage turrets I'm not so sure.
My scopes normally stay on 42x whenever possible. There are times, however, when I'm forced to dial down a bit. Going over ~34-36x on an overcast day is like someone just dimmed the lights, and if the mirage is really, really bad to where I cannot make out anything at all, I may back off to where I can at least center the dot in the big fuzzy black ball.
Most, if not all, of the USA F/TR team is using NF 12-42x NXS scopes so as to have the same adjustments for the sake of making the wind coaches life easier. That way 'come right three clicks' is the same regardless of who is shooting. Not a consideration for most folks, I realize.
