Depends on what you want....
For "take it out of the box and blaze away", the Marlin 60...
If you like to 'customize' your guns, the Ruger 10/22 is very much like the Chevy Small Block V8 Engine...can run it from factory-box-stock to "un-limited" or anywhere in between.
I currently have a 10/22 and an OLD Marlin 99 with the 17-round tube magazine, and I like them both. My Marlin 99 was a $20 pawn-shop-rescue-special. still shoots very well.
