Would you take advice from a cartoons stuffed toy?

Jesus Daniel, how many times in each post do I have to say the only fair/relevant/meaningful comparison is with same generation sensors? It seems like people want to actively misinterpret posts when it is perfectly clear what I was saying and even your linked samples support what I am saying. Technology has moved on, sensor tech is way better now than it was on the first affordable FF sensor, do I really need to point that out?Here's a 12mp 5D FF vs a 24mp 80D crop. There's zero question as to which enlarges better or which could handle more cropping, and it isn't the 5D.

Now here's a 22mp 5D3 FF vs a 24mp 80D crop. About the same despite the sensor size difference (or the slight MP difference).

Of course it will at low ISO. In my experience when post processing crop needs a little more sharpening than FF, but that barely shows here:

Now if all your tests were done at high ISO that would explain it. At high ISO FF is cleaner and retains more sharpness and fine detail.
As for high and low iso, in my experience that is just another function of enlargement. If the ff camera is better at 3200iso (for example) then it will also be better at 100iso but the differences so small as to be irrelevant at a particular size of enlargement, enlarge bigger still and the ff camera will do it 'better'. It's 2.6 times the area so it is being enlarged 2.6 times less, how is this not obvious?
We are not addressing the 'it's good enough' position here, we are addressing the irrefutable fact that for same generation sensors sensor size is king when talking IQ. You yourself have argued many times that pixel size is a fallacious argument when equal enlargement is the comparison.
So let me reframe my point. If I wanted to buy a FF and crop camera with the intention of them complimenting each others capabilities a 7D MkII and a 1DX MkII would make poor stablemates, a 6D MkII and 7D MkII would make good stable mates. If I wanted to make big prints I'd use the 6D MkII, if I wanted to shoot action or was focal length limited I'd use the 7D MkII. A 5D and an 80D would be as foolish as holding them up as a 'comparison'.
