So I've been a happy owner of the Canon EOS M6 Mark ii for about a year now. And I'm about 10000 shots in. When I was in the buying phase I was debating between this camera, and the m50 mark ii. I chose the m6m2 for the better controls and (believe it or not) the removable EVF. I wanted to couple the m6m2 without the evf with the 22mm as an every day carry. I already had some ef(-s) glass from my 100d, so a kitlens wasn't really necessary. I have the Sigma 17-50mm f/2.8 (great lens, just large). This was suppose to be my main lens and then I would have the 22mm for on the go.
I was very happy with the 22mm, very sharp and nice rendering. However, I'm not a 35mm (equiv.) shooter, I prefer 50mm or 28mm. But for the size I thought it was worth the trait off. The 22mm with the m6m2 is not pocket able, for me that is. Those where the exact reasons I sold my 22mm.

Later I bought the Sigma 30mm f/1.4 and a Nikon Coolpix A (as my everyday carry).
The Sigma 30mm is on my m6m2 most of the time. It's a killer combo.

What I like about the camera:
First of all, the AF, it's great. Most of the time I use the small single point AF and it's spot on every, single, time.
Whenever I shoot my cats I use Servo tracking, it works well, but can miss from time to time. Probably user error, so I don't blame this camera.

The IQ is also great. 32.5mp is an insane amount of pixels to work with. I think my sigma lens can only deal with it @f/5.6. But that's fine. The Dynamic range is also very good and the recovered shadows have nice "grain-like" noise.

As for low-light performance, I would say it's pretty good. I would use iso 3200 in every situation. 6400 with some noise reduction (DXO PureRaw is great), and 12800 in certain situations.
What I dislike:
The battery-life. It isn't terrible, but not great. Especially the last two bars drain rather quickly. I can burn through 2 batteries with ease on a single day of moderate shooting.
I'm also not a huge fan of the handling. It's not bad for short periods of time, but when I'm holding the camera for longer than 30 minutes it becomes a bit of a pain. That's why I bought the SmallRig L-bracket. This really helps, especially with larger lenses. I'm lucky since my dad also enjoys photography and has a 70-200 and a 100-400, whenever I loan these lenses I start to appreciate the SmallRig grip more and more. The buttons and dials are really nice and great to use.

The removable EVF comes in handy whenever I'm using a tripod since I don't need it then. Still, I would have liked this camera with a m5 style EVF. At the start I said I bought it for the removable EVF, however, I started using this camera more as a would a DSLR, instead of a pocket camera.

My front dial also has this weird issue where it sometimes just starts scrolling without me touching it. That's why I have turned it off completely since my aperture would suddenly be 1.4 instead of the one I wanted. In menus it's annoying though since I can't turn it off there. Just a note.

I'm very happy with this camera, it can handle almost everything I throw at it. This camera doesn't really inspire me as my AE-1 does, but that isn't a big issue. I will probably use this camera until it's broken since I don't see the value of the M system rising any time soon, and I do not want to sell this camera right now.
TL:DR: Very powerful, can do a whole lot, mediocre battery, lacks personality, great IQ. If you are happy with the current available lenses, buy it.
