While I love me some Canon hardware, when I wanted a smaller full featured camera to pack around light, I went with a used Oly OM-D EM1. Fantastic tech packed into that camera from 5 years ago. Bought it with three batteries, the grip and a 32gb mem card for $369. Paid $200 for an Oly 17mm. So for basically $600 bucks out the door, I have 10fps, ibis, pro features and a lightweight mirrorless that is such a nice feature packed camera that I have no need for a Canon M series ecosystem. Since I have absolutely no need for 4k video in a stills camera, I'm good to go with this Oly.
That being said, that M6 mkII is looking pretty sweet.
