I've 3 .22's at the moment, Ruger sporters 77/22 & 10/22, both purchased prior to the advent of heavy barrels & thumbhole stocks on rimfires. Third is a Savage 94 .22 mag that does have the heavy barrel & thumbhole stock in stainless steel. All are good accurate working guns, though the Savage is the most accurate of the 3.
If I were buying now, I'd opt for a Savage 64 with heavy barrel & thumbhole stock. Mostly as I already have the sporter 10/22, so would prefer to add the Savage as something a bit different though a Ruger 10/22 with heavy barrel & thumbhole would be a great choice as well.
Any fairly well made .22 auto is a good small game gun when it comes down to it. Like any other gun buy, just handle both & if possible fire one of each, then buy the one you find is best for YOU.
So you pays your $$ & enjoy your choice.
