in case you havent used an R (I owned one for a while)
they are super easy to use, touch screen is top notch
LCD quality top notch super duper clear, the 7iii is atrocious in comparison
Gray AF point problems no more, seriously, sony

EVF is top notch, 7iii is atrocious in comparison
20 fps silent mode
E shutter does 1/50 readout, double the 7iii, not super usuable, but more usable for sure
much better ibis
the 24-105 is a stunner, and at that time, cost a good bit less than sony's version
sales..... Canon refurb sales are unmatched by sony, you can get really good prices
going to canon also has major flaws (most often video related), but that's another topic

Don't know, most of these reasons aren't too compelling to me at least. Touch Screen+LCD quality+color of AF point are QoL issues, they don't really matter to whether or not you're getting the picture, though I'd like to have a Canon EVF.
I hardly ever use silent mode (on the RP you had to be on full auto to use it, you only could choose the focusing point, hopefully the R6 is different in that regard).
As for the IBIS, that might be true, but by and large unless you're often shooting at 200+mm with lenses that don't have OSS, not sure why the Sony IBIS is insufficient. I do like Canon IS always being on even when composing, as opposed to Sony only engaging when you press the shutter, but that's all Canon cameras, not only the R6 has that.
"24-105 is a stunner". Sure. I don't know, I've not had the chance to use the Sony version, but I'm sure we'd be hard-pressed to find such striking differences between the two, though it is true that the Canon version is cheaper, and I've personally gotten used to the position of its zoom ring (way too close to the body).
Whatever savings you make on the Canon versions will be more than made up for when you realize that there are very few RF lenses to choose from, and they're mostly upscale professional lenses that are out of reach of most ppl's budgets. And Canon seems to be determined to reproduce its general lens line-up that it had with DSLR, which I'd describe as a prosumer line-up and the upscale professional ones I've already mentioned, with not much for enthusiasts.
Though I'd assume that the R6 would have better body ergonomics, and even with all that is almost CA$1000 more than the a7 III (when the latter is not on sale, right now that's basically $1200), and that for a 20MP body when just about everyone considers 24MP to be baseline. Hard pass if you ask me.
