Here is an interesting Canon EOS R5 review for commercial and portrait photography, and it comes with a comparison to the EOS 5D Mark IV.
The comparison with the EOS 5D Mark IV makes a lot of sense, not least because Canon sees the EOS R5 as a mirrorless alternative to the 5D series. The exhaustive Canon EOS R5 review comes from John Gress:
After using the R5 for a full month as a professional commercial studio and portrait photographer, who shoots some video, I have decided to fully switch from the 5D Mark IV. It took me a while to test everything from auto focus, to tethering to video (including overheating) and how to get the best color out of the new RAW files. This video also covers post production in DPP (Digital Photo Professional), Lightroom and Capture One 20.You can follow John Gress also on Instaram

The EOS R5 seems to be highly regarded as a stills camera. In particular, the EOS R5 autofocus system seems to be huge leap forwards.
