This... 100x this...
I will through this out there as an additional point.
Once you get into the higher end glass, personal preference will come into play.
Some folks prefer S&B glass over other high end glass, and others prefer things over the S&B glass.
If the feature set is correct and the reliability is there, which all of the higher end glass (S&B, Steiner, Kahles, Vortex Razor HD, etc) has, then what your eye prefers is the key.
Me personally? It's really hard to enunciate, but the perception/image of the S&B reticle doesn't really work well for my eyes. I much prefer the image of my Steiners. My Razor GenII also appeals to my eyes better than the PMII that I had for a while.
Buying quality glass is worth it.
