I'm sure someone will chime in with a S&B that they've seen fail, but I've never seen one break. That for me is the main reason to choose one, much like a Nightforce. I have one of the 1.75-6x32 Leupolds on a .375 H&H and it's never given me any problems, but Leupold's reputation for reliability certainly isn't in the S&B category. If I were going to take that rifle on a once in a lifetime hunt I'd much rather have the S&B riding it than the Leupold, no matter what the price.

S&B's work like they're supposed to work and that's something you can't say about a whole lot of products nowadays. They're just a quality scope.
