I guess it comes down to personal preference though I would recommend finding a side by side comparison for each rifle to see the actual size difference between them.
We are talking about a literally a couple of inch's of overall length between the two considering the more streamline narrow stock of the 10/22 compared to the traditional rifle stock of the AR-7 which puts both of these rifles very close in the as far as width is concerned. The Ruger is a lot faster to assemble, has fiber optic sights, a threaded barrel for mounting a suppressor, it's made with extremely durable stainless steel, & carries 40 rounds of loaded magazines between the receiver and butt stock storage compartment plus there's additional storage for another 50 rounds of loose ammo in a watertight grip compartment and an infinite amount of aftermarket support for the 10/22 from replacement parts to major upgrades.
