Canon - EOS R6 Mark II vs Sony - α1 II

The α1 II is the clear pick on raw spec strength, leading by 18.4 points on the Mars Score. The margin is wide enough that the underdog only makes sense if its individual strengths line up with what you specifically need.

Pick the EOS R6 Mark II if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight, af points.

Pick the α1 II if you care most about megapixels and max video. Its strongest claims are megapixels, max video.

Both ship with comparable sensor size, in-body stabilization, log profile, so those specs don't separate the two — focus on the differences below.
