As to user interface, the M interface sucks compared to the 5DIV or even the 6D2, but throw an articulated touchscreen on the back of the mirrorless and you can do an awful lot with just a few buttons. It will never be as good as a full sized body for controls, but it will certainly be good enough... and most certainly better than Sony...
actually the M5 is closer to the 5D/6D interface than any other mirrorless. I can adjust WB, ISO, AF mode, drive mode, focus mode, metering mode, aperture, shutter, EC without really moving my hand off the right grip while looking through the viewfinder and without menu or quick menu diving.
while it's not as good as having the haptic direct control buttons such as the 5D Mark IV, the dial func button and control wheel is insanely useful and the combination just leaves other mirrorless in the dust for control without menu diving.
