Accuracy in the 795 is inherent; the micro-groove barrels work amazing with rimfire rounds. It will easily outshoot a stock 10/22 and the Savage 64, and I have had mine keep pace shot-for-shot against a Brno bolt-action out on the gopher patch.
The benefits of the 10/22 is that you can pay loads more money to make it an even better gun, and their magazine system is quite flexible, but the Marlin 795 now has access to 25-round ProMags which work quite well.
If you want an inexpensive meatgun that will hit what you are aiming at, and do not need any frills or bells and whistles, the 795 is your shooter.
If you like the idea of spending an extra $700 to make a $330 rifle shoot as accurately as the $200 Marlin, then get a 10/22.
