IMO Dial is NEVER more accurate, period, I don't care the brand ,,,,,,
I have used the BEST out there, Swarovski, Nightforce, Schmidt & Bender ,,, they can ALL have problems repeating the dial drop, especially on big rifles ,,,,
THE BEST I have found to use in the field for accuracy and repeatability, even under big recoil is a Schmidt and Bender 4-16X50 Klassic scope with the P3 mil dot reticle in the FRONT Focal plane, so that all hold over lines and dots are accurate at all magnifications ,,,,
