Once again, then Ruger is a modular gun. The exact same receiver, trigger group, bolt, and springs, pins, mag release, magazine, and screws are used with ALL 10/22 models. Barrels and stocks are responsible for the "different models" that you talk about, or the use of stainless.
If you want to be accurate, Marlin has different SKUs for the various stocks, materials, and even scoped models. Your logic is flawed.
Sorry, but I own a stainless Model 60, and an older, blued, Model 60. As noted, they don't feel as well as to fit in my hands. Nor are they as accurate as several of my OEM 10/22 standard models.
For price, Marlin Model 60's, at Bud's, is $164.00 for a blued, birch stock gun. The Laminated Stock, Stainless version is priced at $256.00.
The Ruger 10/22 Synthetic, with a blued finish, lists as $212.00. Bud's has no other standard, birch stocked Rugers, as they are ALL SOLD OUT.
R&R Guns lists the birch carbine gun at $218.30.
While the Marlin 60 CAN be cheaper, it also CANNOT be as easily adapted to a person's shooting style, or needs.
For the person who just wants the cheapest .22 semi-auto around, I agree that the Marlin is probably the best choice.
However, for someone who might want/need a lighter trigger than EITHER gun provides, the Ruger is a hands down winner. Need a stock that lets you scope it? For a left handed person? Again, it's that Ruger.
The 10/22 is much like the AR in the modular aspect. It holds it's ability to be changed into what one wants it to be in good stead. Then, when needs change, it does, too.
I LIKE older .22 rifles, like the 572 and 552 Remington, the Nylon 66, the Winchester Model 190, and the various Mossberg and Marlin semi-autos, like the 99M1, the Model 75, and their ilk. I even own a Model 795 from a decade ago.
My experience, though has been that the Ruger 10/22, through the years, has represented a more durable, accurate, and easy-to-shoot platform.
It's all good. For those with money, I'm sure that the CZ and Anschutz guns fill the same role.
