I just compared it to the 80d as is seems to be the closest crop sensor variant in the canon lineup as it seems to be the most logical - they seem to match the most (like the 7d and 5d series seem to match closely in the pro line up). I could be wrong with both of those comparisons but they share the bodies from looks. For the cost, I would have though the 6dmk2 would have had the same features as the 80d, predominately the headphone jack and all-i video options in the case as a vlogging camera.
These two cameras pair perfectly in my opinion and both are extremely good cameras.
My 80D almost always has my 70-300mm F/4-5.6L lens on it and my 6D2 almost always has the Tamron 45mm f/1.8 lens on it.
(my 16-35mm f/4L is always in my bag and ready for the 6D2 if needed)
This set up for what I do most often is perfect, I very seldom have to change a lens; I just reach down and grab one camera or the other
