Eye-detection AF is huge. It's so difficult to get the perfect portrait. I think most people end up using preview mode and manual focusing, which is a pain and takes a while. I'm not at all unhappy with my choice to get the 6d. It's a great camera, and Canon's lenses have all been great. Even though I've always wanted a smaller full frame, any size improvement to the body is negated by the glass unless you get a fixed pancake lens. Good point about mirrorless battery life as well, I don't usually consider it that much since its easy to carry a spare, but I had an eos-m a while back and the battery life was frustrating. Unfortunately, it got trashed in reviews which I think set mirrorless back a bit for canon. Sure the autofocus was garbage, but the 22mm f/2 kit lens for it was amazing (one of the best I've used) and it was the smallest inexpensive camera with the best IQ/$ imo, and it had an aps-c sensor. The rest of the competition was doing m4/3. I remember you could pick up the kit for around $250 or so shortly after it came out.
