Analysis:

The Canon EOS R3 (2021) is one of the very best Mirrorless Cameras that one can get for around $5,400. The Sony α7R IVA (2021), however, while a very good choice at its $3,000 price point, falls just short of being remarkable.

The Canon EOS R3 (2021) has done great in a couple of roundups conducted by highly trusted sources that perform objective in-depth testing, like CNET, PCmag, Digital Camera World, and The Phoblographer - it earned the "Best fast-shooting pro Canon camera" title from CNET, "Best High-Speed Camera for Sports" from PCmag, and "Ranked 1 out of 15" from Digital Camera World. Any product that's held in high regard by such reliable sources should be considered by anyone that's looking for a Mirrorless Camera at this price point.

As for the Sony α7R IVA (2021), it wasn't able to earn a top spot in any roundups from trusted sources that conduct their own hands-on testing. Nevertheless, it managed to impress reviewers at PCmag, Digital Photography Review, Digital Camera World, and shotkit.com enough to make it onto their respective shortlists.

We conducted an analysis of all of the review data that we could find on these two products. First, we focused on sources that tested and rated both of them, like PCmag, and learned that they all showed a preference for the Sony α7R IVA (2021).

Then we took a look at the highest review scores that these two Mirrorless Cameras received. We found that the Canon EOS R3 (2021) managed to earn a rating of 10 from ePHOTOzine, whereas the Sony α7R IVA (2021) got its highest, 10, score from reviewers at PCmag.

Lastly, we averaged out all of the reviews scores that we could find on these two products and compared them to other Mirrorless Cameras on the market. We learned that both of them performed far better than most of their competitors - the overall review average earned by Mirrorless Cameras being 7.9 out of 10, whereas the Canon EOS R3 (2021) and Sony α7R IVA (2021) managed averages of 9.3 and 9.6 points, respectively.

Due to the difference in their prices, however, it's important to keep in mind that a direct Canon EOS R3 (2021) vs. Sony α7R IVA (2021) comparison might not be entirely fair - some sources don't take value for money into account when assigning their scores and therefore have a tendency to rate more premium products better.
