For portraits, I can certainly work with the 6D. I have a grandson who will soon be involved in indoor and outdoor sports. The 6D is a very nice camera, but AF is not very fast. I also occasionally need the flip view screen.
For me, the question is whether the 80D will improve AF and imagery over the 60D enough to justify the added expense. I am very happy with the sensor of the 6D, but I recall disappointment with the shooting speed when I first got it.
The 80D is a significant improvement over the 60D in many ways. It's not that costly either. If you sell the 60D for a little bit, and get a Canon Refurb 80D, you really won't be putting out a ton for one which can soften the expense. The AF is much better. The low light focusing is much better. The ISO performance is better. If you were to perfectly expose two exact images with the 60D & 80D and look at them scaled down to the size of a monitor or tablet however, you'd be hard pressed to know any difference (and this applies to the 6D and one of these cameras, or most cameras frankly). So the improvements are mechanical and ISO, and while yes the sensor has improvements in dynamic range, unless you're processing that up, lifting shadows, etc, commonly, you'd never have known.
Very best,
