I have owned or own both scopes. The 1.8-5.5x38 is the best scope I've looked thru in a long time. Much better to me than the 3-9x40. The 3-9x40Zeiss is good glass but has a flare to me when I look thru it. The 3.5-10x40 Leupold is a sleek yet excellent glass for any hunting anywhere. It covers a multitude of variables and circumstances. I ordered mine from the pro shop w/a post and duplex reticle w/the center cross hairs cut to .6 which is the same diameter as their 6x42. The custom shop's offerings and their warranty are qualities that just can't be had in any other scope. powdr
