I don't have either scope, but I do have a Steiner 3-12x56 Military. I'm very happy with the scope and I want to buy a the new Steiner 5-25 when it's out. From what I've read, there are only subtle differences that make the S&B better, and there are subtle differences that make the Steiner better. If you have the means to buy the S&B and won't feel the difference much in your pocket then get the S&B. If you are trying to save a good chunk of money and get a scope that's 99.5% of the quality and performance of the S&B, then the Steiner is what you want.
