I'll probably be picking up a M6 II later today. I use the M3 for my EOS-M/"small kit." I've been debating getting rid of my entire "M" kit as I mostly use my G7X II or 5DIV, or upgrading the M3 to the M6 II for better AF, lower light focusing, etc. Still teetering just a bit, but most likely going to pick it up and give the EOS M more of a chance. If nothing else, the M3 with external mic has become my go to video camera and the M6 would be better as the M3 has struggled with low light AF.
