Optically the 2-10x42 I've been using is very good. I don't have any truly high quality glass to compare it to, I use mainly SWFA 6x's, Leupold 6x's, and various 4x's. It trumps all of them optically.
One thing I really like about this model is how it is very easy to get behind and is non-critical. Nice open window view much like a 6x42 Leupold. It gets a little tighter at 10x, but even there I feel like it has more wiggle room than the SWFA 6x42 (which isn't bad)...why I don't know but it seems that way. That's important to me in a hunting scope.
