For the shear parts availability, and compatibility with ARs & ease of modification with no real knowledge of 'smithing required, the WK wins out.
From what I've seen the WK is, out of the box, more accurate than VZs I've seen, and there is always the ability to spin on an even better quality barrel.
You can float the barrel, add optics easily, run irons or optics or both. Accessories are easily added and/or subtracted.
With RWA's additions, you can have it in multiple calibers; .223, .300 blackout, 7.62x39, and likely more on the way.
The 180 design is every bit as reliable as the VZ platform.
The original VZ-58 in 7.62x39 is a cool Cold War era milsurp, but anything other than that is wanting in my opinion.
