The new Marlin's are really nice actually. I'm a member over at Marlinowners.com and the complaints about QC have gone way down over the past few years. The new Marlins I look over at my LGS are really nice rifle. And I've owned over 20 Marlin levers so I know what I'm looking at.
The new Winchesters are top notch. And I'm a pre 64 guy. You can't go wrong with either one. I'm not just a guy that owns a lever action. I'm a lever action guy. To hell with bolt guns.
