Which should you buy?
The α6700 edges ahead on the Mars Score (42.8 vs 47.6), but the 4.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the OM-1 Mark II if you care most about af points. The biggest gaps in its favor are af points.
Pick the α6700 if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight, megapixels, sensor size, among others.
Both ship with comparable in-body stabilization, log profile, 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.
