Ruger mini 30 is more accurate, but power's the same. AK can be cheaper, and easier to clean. Mini 30 is a ruger(some people like rugers). Pick neither. An sks is what the ruger should have been. Also 7.62x39, but way better. The reliability of an ak( made by same people), and the accuracy of the ruger. Also, usually about $200-$300. By far the cheapest. But of the two you said, I'd take the ruger. I hope this was helpfull.
