Don't understand this quote - I have both and performance differences are negligible - it is in customization where you see a noticeable difference.
In my experience, accuracy is a wash. Therefore, accuracy can be thrown out of the equation. In terms of reliability, the 10/22 wins hands down. As for handling, the 597 feels big and cumbersome, whereas the 10/22 is light and easy to manipulate. As mentioned above, aftermarket goodies abound for the 10/22. The 597 is a decent .22, but there are better options. And like I said, it just can't compete with the 10/22.
