I don't own either but have looked thru both. When I was looking for a scope for my 17hmr I looked at several brands of scopes around the 400 dollar mark. I personally liked the ziess better than the leupold. I thought the optics were clearer and the construction was better over all. The Zeiss scopes just felt better, more like camera optics. The leupold I looked at was stiff and gritty when you made adjustments to it.

I actually ended up getting an alaskan guide model from cabelas because it offered more features that I wanted for the price (higher power, A/O, and mildot).

But like I said, I am only going by what I saw in the store comparing them side by side.

And by the way, I have Carl Ziess lens coatings on my driving glasses. Walmart has a contract with them and offers it exclusively from what I understand. They seem a bit crisper than my reading glasses that are the plain poly lenses. Almost like I'm not wearing glasses. However glasses have improved greatly in the past 10 years or so any way from what I have seen. I don't know if it really helps or not, but it sounds cool.
