I'd take a VZ over an AK any day. The only reason I'd ever pick an AK over a VZ is if I were in the US and needed readily available mags and parts.
But if I were choosing between AKs and VZs in a vaccuum, I'd take the VZ without thinking twice. AKs are heavier, possibly less accurate although good enough for government work as the saying goes, the ergos suck and I hate the safety and the lack of a bolt hold open. Stovepipes are virtually impossible on a VZ and clearance drills are almost pointless. If you get a f**ked AK mag and it pukes rounds, double and triple feeds can get really nasty. FTEs can be really ugly in an AK as well and AK reliability is sufficiently overstated/mythological that people don't realize...these things happen on AKs as well and they SUCK to fix.
Damn right I'd take a VZ.
