Which should you buy?
The α7 IV edges ahead on the Mars Score (46 vs 52.8), but the 6.8-point gap is small enough that the right pick comes down to which spec advantages matter to you.
Pick the EOS R6 Mark II if you care most about af points. The biggest gaps in its favor are af points.
Pick the α7 IV if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are megapixels, weight.
Both ship with comparable sensor size, max video, in-body stabilization, so those specs don't separate the two — focus on the differences below.
Bottom line: the α7 IV is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
