I haved owned leupold, burris and zeiss. I currently have4 zeiss conquests 3 of which sit on top of my main big game hunting rifles, the leupolds are nowfor mysafe queens!I guess you can say I prefer the conquest to the VXIII's both optically and functionality.... In terms of holding POI and tracking my conquests have been spot on( currently these 3 top; 7mm rem mag, 338wm and 50 cal ML).

I concur 3x9/10 mag.is a good balance for big game usage.
