I have a Egyptian Madi, Serbian, Romanian and others they all shoot great. But my Mak-90 is a step above the rest.
The Chinese build some exceptionally good AKs, but most are valuable to the collector and quiet pricey. The 56s is my favorite AK rifle, but I wouldn't take it out and run several thousand rounds through it. I'd buy a wasr and run the crap out of it.
