I'm a financially terminal generalist collector/gun-nut, so I like my AR, and AKs, and SKSs, and Mausers, and Mosins, and...
For long range gong-ringing or paper-punching my AR beats my AK, in my hands. The AK has more of a no pretentiousness, feisty street-fighter feel to it, and wood furniture, and some history. My DD M4gery with no actual military-used parts doesn't have much of a historical feel to it, though it's backed up by plenty, but I still admire it's interesting and very different modular design, tight mil-spec tolerances, and tack-driving ability. Best of all, it makes me feel like a marksman
Limiting the conversation to SKS, AK and AR, the SKS is hard to beat for history, since unlike any AK or AR that I'll ever own (I don't have hundreds of thousands of dollars to build that type of collection, but love to look at others collections who do), all of my SKSs are in original military configuration. The milled steel and simplicity of the SKS says robust performance and the wood stock says history, unlike any aluminum and plastic gun ever will
