I, too, remain primarily a Canon person. I have Fuji and Sony (as well as Phase One until recently) in my closet as well, but time and time again I still make my best images with the Canon equipment (5d4 or 5DSR) and a small selections of zooms (16-35, 25-104, and 70-200). Why? Because I'm not really limited by the technology of any specific camera, but I'm a "loose" shooter (even on my paid architecture gigs), and for me having to worry about the camera itself plays havoc with the flow of my seeing and my shooting. Same with my lenses. I guess I'm sacrificing some iota of ultimate quality with the zooms, but being able to scale the image and shoot for "feel" produces better images for me than stopping to think through the body/lens/dynamic range equation.
Sure, maybe Canon isn't cutting edge like the newest Nikon or Sony stuff, but I have yet to see what I'm losing at the edges of the sensor's capability.
