Our verdict
Both fit low-clearance cars; the difference is bite, durability, and price. The Super Z6 cable chain installs fast, self-tensions, and is all most drivers need for a few pass crossings a winter at a quarter of the cost. The König is a real 12mm link chain that grips glazed ice and deep snow far better, tensions itself as you drive, and lasts for years of frequent use — a mountain resident's chain. Occasional use: Super Z6. Regular use on real ice: König.
