Fujifilm - X100VI vs Sony - α9 III

The X100VI is the clear pick on raw spec strength, leading by 11.7 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 X100VI if you carry the device everywhere and weight or thickness has been the deciding factor before. The biggest gaps in its favor are weight, megapixels, max video.

Pick the α9 III if you care most about af points and sensor size. Its strongest claims are af points, sensor size.

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

Bottom line: the X100VI is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
