How does the Bushnell 4200 series scopes stack up against their competitors, specifically the 4-16x40 and the 6-24x40? I own several scopes including Zeiss Conquest, Leupold VX-III, Nightforce NXS, and the Nikon Monarch. Would the Bushnell 4200 be comparable in resolution to any of these scopes. How about the tracking?
