Here is a Canon EOS M6 Mark II review by DPReview, and they call it their “favorite Canon mirrorless camera yet“.
From their conclusion:
The Canon EOS M6 II is a more overtly photographer-targeted camera than its predecessor, gaining Dial Func control, a dedicated MF/AF switch and an AF-On button which combine to put just a little more control directly at your fingertips. And it ends up giving a good degree of direct control without the sense that you need to completely configure the camera yourself.[…] The camera’s autofocus isn’t quite a match for Sony’s a6400 and a6600, but it’s still very good and will adapt to a wide range of shooting with little effort. […] the M6 II is an excellent choice. It’s not the best in its class in every respect: the Sony a6400’s autofocus is better, the Fujifilm X-T30’s video is superior, as is its lens range, while the Nikon Z50 arguably has nicer ergonomics. But the M6 II does have the highest resolution of the bunch with excellent noise performance and dynamic range, and is otherwise competitive across the board. Above all, it’s engaging and enjoyable to shoot with. Read the Canon EOS M6 Mark II review at DPReview
