I have no complaints about my Leupolds for durabilty and optically they aren't no slouches either. However both my most used hunting firearms now wear Zeiss and they have the loopy when it comes to clarity, brightness. I also like some of the features the conquest has like Constant Eye relief andz-plex reticle. I have only had the Zeiss for a few years but they have been rock solid in every facet.

I would pick the Zeiss but your best to judge them yourself and then make your pick. Either one are good quality optics and should serve you very well.

Enjoy and good luck with your new setup
