AK / AKM cons:
>mediocre at best accuracy
>manlet length of pull
>kind of terrible sights
>no LRBHO (can almost get there with Yugo mags, but not quite)
>rainbow trajectory
>magazines are kind of awkwardly shaped, little awkward going prone with
>can't reach selector without breaking grip
>no ready way to mount optics on old milled AKs, later AKMs with the side mount are about as gracious and sleek as the G3's claw mount, ergo not really (the top cover is kind of awful)
>MP40 style underfolding stock on AKS and AKMS is uncomfortable as fuck to shoot
>Romanian/East German wire sidefolder doesn't loosen up in the same way, but feels similarly awful
>Bulgarian AMD65 has a barely nicer sidefolder but is instead a shorter carbine with a brake which habitually rapes your hearing during field exercises
>Yugos have no chrome
AK / AKM pros:
>larger magazine capacity than G3, and can easily carry twice the ammo, later bakelite mags mean the load is even lighter than before
>recoil is easy to manage, short and long salvos are both a breeze, rapid single shots are trivial
>manages to have a better reload than the G3 in spite of not even trying
>still pretty good barrier penetration with that heavy bullet
>famously durable, fairly easy to unfuck if it gets fucked, even the dumbest conscript would struggle to ruin it
>Yugo mags at least have that partial LRBHO I guess, and very conducive for launching grenades
