The age-old debate of Marlin 60 vs. Ruger 10/22 is like arguing Ford trucks vs. Chevy trucks. Both are proven designs with rabid followers. Really comes down to personal preference. A weakness of one is balanced by an advantage it has in another area over the other.
Me, I've shot and liked several examples of both but own a Marlin 60. Why? I just liked it better on the "test drive".
