Canon King of high ISO? I take it you have never used a Nikon Df or Sony A7s? Those are the kings of High ISO. Canon can't touch them not even with the 1Dx.
Be careful bringing the truth into these arguments... 
Honestly though, the difference between the 5D3, 6D, 1DX, D750, Df, D4s or a7S are all pretty much as near as makes no difference at ISO12800 imo. The 1DX, Df, D4s and a7S definitely have the edge beyond that though, but again, I think they're all very close to each other at those crazy high ISO's.
