Canon - RF 50mm f/1.2L USM vs Nikon - NIKKOR Z 24-70mm f/2.8 S

These two are nearly even on the Mars Score (57.6 vs 55.3). The decision isn't about overall quality — both clear the bar — it's about which specific trade-offs fit your use.

Pick the RF 50mm f/1.2L USM if you care most about min focal. The biggest gaps in its favor are min focal.

Pick the NIKKOR Z 24-70mm f/2.8 S if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight, max focal.

Both ship with comparable weather sealed, optical stabilization, so those specs don't separate the two — focus on the differences below.

Bottom line: there is no wrong answer here — match the spec advantages to how you actually use the product. The Mars Score parity tells you both are well-rounded; the differences are about trade-offs, not quality.
