I knew that this would trigger you. LOL.

But seriously - when I look at the IQ comparison thingy in dpreview, the M6 II produces much higher noise levels than its 24mp peers.
Of course, that's not unexpected but it also shows that 32mp and high ISO don't go together - just as 50mp+ for FF (and to ease your pain - that also applies to the A7R IV).
You may argue that you just need to scale down but this defies the purpose really.

Compared to MFT, Sony and Fuji, the EOS M lens lineup remains poor - there isn't even a "24-xx" zoom lens and nothingness in the long tele segment.
And sorry, adapters don't count in my book - adapters are just a pathetic attempt to hide the fact that native lenses are just not available.

But seriously, when you look at photonstophotos, you (should) realize that when printing at the same size, the noise is similar, and only in high ISO scenarios noise would be apparent. So what does the higher res. bring you? Higher res. when you want to print bigger. So, similar at high iSO and same size printing, advantage when printing bigger especially with lower ISO. 

Weird how every step up in resolution since 6mp (or probably before that too) triggers the same response from you... :-P

No idea why I would need a "native" tele lens on EOS M when with the simple adapter things work just fine. Must be my sensible nature.
