Tube-fed are a pain to unload without shooting all of the ammo out the barrel.
The Ruger has the best magazine ever invented for a 22.
This. But it is a personal thing and in this case the magazine design speaks volume to me. I like both the Marlin and the Ruger but if I was going to buy just one I would pick the Ruger. I also feel that the Ruger holds there value better but that is just my opinion.
