6D vs 80D, to me the 80D wins this contest hands down. If there is a slight advantage to the 6D it would be at the highest, not just high, ISO settings especially since the 6D has a larger ISO range. That slight advantage can be eliminated totally with the correct choice of lens such as the Sigma 18-35mm f/1.8 DC HSM Art Lens. This is would be more true if the 6D user is using a f2.8 lens.
The main advantage why the 80D is better is it is newer. Newer generally means better tech in the design. The FF 6D has a 20.0MP CMOS sensor but it has a modified DIGIC 5 processor. The 80D has a 24.0MP APS-C CMOS sensor with the more advanced DIGIC 6 processor. The tigher pixel density of the 80D should provide better IQ again depending on lens choice. The 80D has better DR and is better weather sealed just for kicks.
If you were comparing the 80D to the 6D Mk II it is a totally different story. My 2 cents and worth every penny.
