IMO the DNZ Game Reapers are better in some ways IMO. The DNZ will not mar your scope and have a true alignment. The Tallys are a bit lighter and slimmer. I have two DNZ mounts on rifles and Talley Lightweight rings on another. Both the DNZ and Talley LW mounts are ugly. The choice is like between a chunky ugly gal and a skinny ugly gal. In the end neither will win a beauty contest.
DNZ low mount on my M70 FW 30-06 with a 6x42mm Leupold.
DNZ on my Rem 660 with a Leupold fixed 4x.
