I personally voted for the Nightforce because it simply is my favorite scope.
Why? It is built like a TANK, it has OUTSTANDING RESOLUTION, it has INCREDIBLE LIGHT TRANSMISSION, and it has the absolute FINEST ILLUMINATED RETICLE SYSTEM on the market.
The only things that I do not like about it is that it is heavy (at 32 oz.) big and long (it has 56mm objectives) and is pricey (over $1,300).
Still, it's an awesome scope and my favorite.
I must admit, however, that, for all practical reasons, the BUSHNELL ELITE 4200s are some of the finest scopes on the market, even regardless of price, and I absolutely love the RAINGUARD feature. These are my second favorite scopes.
My third favorite scopes are the Nikon Monarchs (pretty much identical to the Elite 4200s except that they don't have rainguard), and the Leupold Vari-X IIIs.
