I recently had a similar experience in that I returned a Golden Ring HD, was informed they could not be fixed and offered the new McKinley as a replacement. Granted my sample size of experience with the two models is n=1 of each, to my eyes the McKinley's are clearly superior. I like sharp edges, and they are indeed sharp to the very edge of the FOV and comparable to my Nikon SEs in that regard. The GRs were not. Other than that I'd say, for the two Leupold specimens I have owned, it's a toss up.
