They all make good ones and bad ones. I'd have to say Nightforce is pretty impressive. I've been using them for last couple years and they are pretty tough.

I have 2 other scopes that have proven themselves thru the years.

3x9x42 Zeiss Diavari that has been on my primary deer rifle. Has had the crap beat out of it for 12-13 long deer seasons and has held up beautifully. Shot it last week, still dead on after all those years.

Leupold VX6 1x6x24. Has been on different 375s and to Africa 4 times and Kodiak once. Has taken an incredible beating on those safaris, brush trucks, bush planes, boats, you name it. Never let me down.
