VZ is better than the AK in every way... Lighter, probably as reliable, easier to field strip, better ergonomics, has a hold-open feature and probably won't burn you as much when hot (I can't say for sure because I've never tried it in the USA with real mags...)
The only thing going for the AK is the stronger and more abundant mags... And the cool factor.... When shooting FA, the AK gets real hot and you better have gloves on! In the USA, they are cheap and plentiful... Here they are nice safequeens that can't even be shot at a range...
The SKS is not in the same category as it is not an assault rifle... But it is built like a tank (actually antitank!), is cheap and reliable. With the original 10 round mag, it is better than most rifles of the era and is quick to reload with the clips... The D model is great with the AK mags but there is no point in Canada with 5 rounders....
