The FE 24-70mm f/2.8 GM II edges ahead on the Mars Score (51.9 vs 55.3), but the 3.4-point gap is small enough that the right pick comes down to which spec advantages matter to you.

Pick the 35mm f/1.2 DG DN Art if you care most about min focal. The biggest gaps in its favor are min focal.

Pick the FE 24-70mm f/2.8 GM II 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.
