I have a Ruger 10/22 and a Marlin 60. Both are fun semi-auto .22 rifles good for plinking, but my Marlin 60 is more accurate than my Ruger 10/22. The Marlin 60 also holds more rounds in its tube magazine than the Ruger 10/22 does in its rotary magazine. I find that I can load the tube faster than I can reload the rotary as well, so... if you're comparing a Marlin 60 to a Ruger 10/22 with only one rotary mag, then the Marlin has a higher ammo capacity and a faster reload time. Once you get multiple magazines for the Ruger, the Marlin's reloading advantage becomes less important. The good news is that both the Marlin 60 and Ruger 10/22 are so cheap that you could just buy one of each and enjoy two fun rifles.
If you want to put a decent sum of money into your .22, the Ruger 10/22 is just about the most modifiable .22 rifle on the market. There are so many companies producing aftermarket parts for the 10/22 that you can basically customize it to suit any taste. They may not be the most accurate rifles out of the box, but if you take a cheap 10/22 and dump a heap of custom parts into it, you could easily have a tack driver.
If you don't want to go semi-auto, a CZ bolt action would be a good choice. They have a reputation for accuracy and quality.
My dad has two lever action .22 rifles. One is a Henry and the other is a Marlin 39. Both cycle smoothly and are a blast to shoot, but the Marlin is definitely the hands-down winner in accuracy between the two.
