When stating a particular rifle is better " overall" is a way broad brush with which to paint.
Having sks's from Yugos, arsenal refinished Russians, and norinco, I will attest to there durability. They will indeed ho bang, and occasionally very rapidly when that ' cheaper ' ammunition pops a piece of primer onto the firing pin channel. They are apparently " better " when firing at game or varmints as well. Annoying a prairie dog at 250 yards hoping to actually strike one must be" better " attempting to harvest, say an elk at 400 yds would be amusing as well, not that it would be nearly impossible to strike one, on the odd chance that a 6-12 minute rifle could, but the terminal ballistics would then be very suspect. I presume that's " better ' too?
An sks does have a viable place in shooting, and can be equipped with a wonky scope fixture to hopefully increase the usually poor accuracy. It can be customized to have all various kinds of things on it and can be fun to go blast away with. It accomplished a role and was abandoned after it was obsolete. Still fun. Still ( kinda) cheap.
I wont be drawn into arguments regarding ' better', but will assert that with lighter projectiles my M1a has accounted for dozens of prairie dogs at ranges further than 250 yds quite regularly. With standard weight bullets coyotes, more prairie dogs and several elk have been taken with mine plus antelope and deer. And also several hi power matches with the rock solid optics removed, but oddly I never saw an sks on the firing line. Let's now discuss the slew of " expert" opinions regarding a long serving US rifle, I'm not in the military any longer, and would doubt that most posters here are either, so that particular discussion is mute in regards to the new roles of each rifle in its sporting role today and if comparison is to be made perhaps fellas that actually served with and against either would be more practical. I missed the M14 by a coupla years so my opinion of it as a combat rifle are academic
