I voted good. I like my SKS rifles, but prefer my AK's to them hands down. It all comes down to the low capacity. My yugo SKS runs like a swiss watch, but only holds ten rounds. My Chinese ten round rifles run just as well, my M model 20" rifles have issues, they are fairly reliable, but mag changes are not as quick or easy as an AK, they also are not quite as reliable and either my AK's or fixed mag SKS's.
All the same, if a person just cannot afford an AK, the SKS is a great alternative for half the price, if you already have an AK and not an SKS, you need to go and buy one, because they are a blast. This is an issue where the owners personal preferences make more of a difference than the actual pro or cons of the rifles, and as ususal you are doing yourself a disservice if you don't get both.
