Monarchs are great scopes, however I'm not very familiar with the Zeiss line. Just make sure you are comparing apples to apples. Monarch in it's price range it a great optic, it seems the Zeiss you are looking at may be a higher priced line. If you want to look at a higher priced line of Nikon, check out the Monarch X, Premier, or even the new EDG line (EDG are very the best Nikon offers and yes, they are expensive but are AMAZING!!) It all comes down to what looks best to you, all of our eyes are different, and what looks good to you may not look good to someone else. Look through the ones you like and pick the one YOU like best!! Good luck
