I own both. When I hit the range for some paper punching the marlin is the one I take. When I am just out at the farm can dancing the mossy gets some attention. While I am a mossberg fan, I am also a Marlin fan.
There is no comparison between the mossy 702 and Marlin 60. Marlin wins in accuracy, fit and feel every time.
However, on another note, if I take my Mossy 151MB I spend just as much trigger time with the 151 as I do the 60.
