Both Zeiss and Swarovski glass in their high end lines are spectacular. Life doesn't get any better when the choice boils down to deciding between great and great!!! The high zoom factor technology, first 6 and now 8!!!, is remarkable when one ponders the notion that this comes with a wide field of view and crystal clear glass. Long ago I came to despise anything that offered less than 75 foot FOV at 100 yards, and have in more recent years reset my personal minimum expectation to over 110 feet at 100 yards FOV who set to the low power zero magnification setting.

I do absolutely love the Z6 and Z6i and they are my current choices for adorment of the tops of my bolt action hunting rifles. Nobody in Canada seems to stock the Zeiss 1x3 or other such zero magnification Zeiss kit, so I've only been meaningfully exposed to the 1.5x6 Victory / Diavari models which are also marvellous indeed, ignoring the crappy (in my opinion) FOV.

I have no use for super high magnification and heavy glass on any of my hunting rifles, but on the target range it is a different story. My pocketbook sensibilities have limited me to using Leupold glass for high magnification target range applications. Pity, because Zeiss and Swarovski are at least to my eye so very much better from an optical quality perspective.
