Owned several of both and I like the ak because of the detachable magazine and it can hold more rounds than the stock box 10 round mag for the sks. I do like the longer sight radius on the sks too. They are both easy to break down and clean. I think the sks is much cheaper than the ak right now, but they are getting super expensive too. I had 5 sks's at one time but kept my Russian and chinese paratrooper. I never owned a Siaga, but I hear they are super nice and accurate ak's. I always wanted to get a .308 Saiga, but they are hard to find. If you can get the Saiga, you can't go wrong with one of them, jump on it, they are really nice.
