I sure wouldn't call the Ruger far superior at all. It is a great rifle though just a little different and if that's what your looking for then that's what you should get.
Marlin 60c
positives,
Cheap, you can find one new for just over $100.
Tubular magazine, they are great and reliable if that is what you like.
Accurate out of the box so not much need to modify.
negatives,
Tubular magazines, no high cap for this rifle.
Not much aftermarket for the rifle.
Ruger 10/22
positives,
Resale, even used it retains it's value pretty well.
Detachable magazine, great if you looking for a high cap magazines or if you want to carry several already loaded.
Customizable, the aftermarket is so big for the 10/22 you can literally change every part on the rifle if you want.
negatives,
Expensive, twice as expensive as the Marlin.
Not as accurate out of the box. Probably.
Detachable magazines, can be a pain if they don't work right and if you buy several it is another added expense.
Customizable, can be good or end up being a money pit you will never get your money back out of if you want to sell.
