Between the EOS R1 and SL3, the EOS R1 comes out ahead in af points, while the SL3 wins on weight and megapixels. Overall, the EOS R1 scores 46 and the SL3 scores 70.8 on our Mars Score.
Which should you buy?
The SL3 is the clear pick on raw spec strength, leading by 24.8 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 R1 if you care most about af points. The biggest gaps in its favor are af points.
Pick the SL3 if you carry the device everywhere and weight or thickness has been the deciding factor before. Its strongest claims are weight, 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.
Bottom line: the SL3 is the safer default. The other model is the right choice only when its specific advantages line up with your priorities.
