Just my opinion, of course, but the anti-Canon bias will no doubt hurt Canon's bottom line, and thus hurt all the Canon users - at least in the short term. If two card slots makes up for lousy ergonomics, then I guess Sony is best. If IBIS makes up for sub-par color, then I guess Sony is best.
Dustin Abbot has a nice review, not sure if it has been linked in a thread or not:
https://dustinabbott.net/2018/12/canon-eos-r-review/
In it, he mentions some things I agree totally with:
"First of all, it feels fantastic in the hand. The grip is far and away the best that I’ve encountered so far on a mirrorless body, and I think Canon has the right idea about the size and form factor of this camera." And, "What’s also worth noting is that the design allows for adequate room for one’s knuckles between lenses and the grip – something that the a7R3 often cannot say."
Another aspect where Dustin finds Canon in the lead: "The EOS R has Canon’s fully articulating screen, which will undoubtedly make this camera a popular choice with vloggers and those that want a simple monitoring solution when facing the camera. The screen can be manipulated into a number of positions, and I find Canon’s articulating screens very useful. It is made further useful by the fact that Canon makes the best camera touchscreens in the business."
Another area that Canon is best: "If you look at the front of the camera you will notice a couple of things, including one of Canon’s most clever innovations on the EOS R. It is a shield that comes down in front of the sensor to keep dust off it when changing lenses. This purpose is served (in an inferior way) by the mirror assembly on DSLRs, but this is a cleaner solution. This has been an area of intense vulnerability for my Sony a7R3, which is seemingly in constant need of cleaning."
About the EVF: "The viewfinder on the EOS R is excellent. It has the higher 3.69 million dot resolution (like the Sony a7R3 and superior to the a73). It is clean and natural looking and a joy to use. I find the higher resolution particularly useful when magnifying an image to manually focus."
I've had a chance to look through the EVF of the 3 mentioned cameras and find the Canon to be noticeably better.
Dustin does consider the lack of IBIS and the lack of a 2nd card slot to be a considerable negative. Like all fair reviewers, he does mention the good and the bad. But in some respects the Canon is industry leading. And - as in all things about specs - each user will have priorities, including specs that are absolutely necessary and others that are completely non needed. I would argue that DPR puts far more emphasis on specs that are considered important or necessary by a minority of users (IBIS, 2 card slots) and puts little emphasis on things that are important to far more photographers (ergonomics, color).
As in all things, each person should base their opinion on actual experience if possible. The popularity of these types of sites gives them far too much power in the industry in my opinion. That alone should make them suspect - even if their biases are only subconscious.
