I'm torn here. I've owned three 10-22s, two good, one a real stinker, a Model 60, a Nylon 66, and a Marlin 795.
The 60 was my very first, and I shot the snot out of it in my teens and twenties, so I'll always look at it favorably. That said, I'm not a fan of tube magazines for safety and would prefer a removable box mag instead.
I wish I could like the Ruger more, but for me, it never 'fit' right for me, and I was never into the tacti-cool thing like some folks are.
I won't speak much of the 66 other than to say I enjoyed shooting and handling the one I (briefly)owned, but as with the 60, there's the tube mag safety issues mentioned before. They have their place and advantages over box mags, but I go back to the safety issue again.
Based on the list, form factor, and price of base unit and peripheral gear, the 795 is probably the best for me in this category.
You'll notice I don't include the AR-7,of which I've owned four. While I had one good one, none come close overall to any of the other rifles listed, because their only real advantage is their one-trick take-down and storage ability, which while handy and desirable in some circumstances, overall, they were crappy rifles accuracy and reliability wise in my experience.
