I am very late to this and I'm sure the OP has already made up his mind(I'm too lazy to read the entire thread) but I'm going to put in my .02 anyway.
I'm owned the bottom of the barrel AK and I now own a type 56 factory 26 SKS. the AK was complete and utter garbage. yes it'll hit a man at 50 yards no sweat but hitting at deer at 100 was almost outside it's abilities from sandbags no less free hand with outside variables coming into play. the thing was a rust bucket, the mag wobbled, the front sights were canted, it kicked like a mule, and it horribly unreliably unless you spent the extra money on crapco and Peemags.
I spent 3 years and well over 1000 rounds trying to make myself like it, and when that failed I tried to adapt it to me... that failed just as badly. so I sold it for a loss and never once regretted the decision. now I own the SKS, when I got it, the stock was horribly shrunken and I did not want to try and work with the sights which are the same as the ones on the AK47. I upgraded to tech sights, swapped out for a ramline sporter stock and just to keep it legal I went with a crapco 20 round mag. the thing will hit pill bottles full of tannerite at 75 yards almost without effort. I have never once found a speck of rust inside it, I have now tried the factory 10 round, crapco 20 rounder, and most recently a 20 round fixed chinese mag. all have been 100% reliable.
it is MY OPINION, based on limited personal experience with the AK and SKS that the SKS is far superior to the AK especially considering the price differences involved. for everyone claiming that you can't compare a single rifle of one to a single of another and expect it to be an accurate representation of the total market. I grab every SKS and AK I see on the racks for the sole purpose of comparison. with the exception of mag wobble and canted sights, there is no difference in the fit/finish of an arsenal AK47 and a century, no difference in the ergos, no difference in the triggers, they are, in MY OPINION, a waste of extra dollars. as for the sks, I will conceed that too many people try to make it something that it is not and put the crapco T6 stocks with M4 telescoping stock and pistolgrip on it and they essentially ruin the essence of the SKS and turn it into a clunky, bulky rifle that has little practical application but in proper configuration with proper sights, it is a wonderful rifle and one which I would take any day of the week over an Arsenal or other top tier AK...
... OK I lied, I would take the AK, sell it and then buy the SKS and a few thousand rounds instead.
