I bought the Canon EOS R3 as my mirrorless hybrid body because it finally matches the way I shoot—street plus client photo/video. The smart controller, the quick photo/video toggle, and the fast sensor readout make it feel like a proper pro tool, not a compromise.
Pros
+Fast readout electronic shutter with minimal jello in my testing
+Great 4K and lovely 6K RAW results
+Smart controller and quick photo/video switch fit my workflow
+Flip screen adds real flexibility for shooting angles
+Better low-light headroom (about a stop vs my 1DX Mark III)
Cons
-1080p looks really bad to me (over-sharpened, like upscaled 720)
-Eye Control AF feels more like a gimmick than a daily feature
