The problem that arises is that statements like "blows away" are very subjective, perhaps exaggeration, and almost meaningless without the photos that demonstrate the difference. To really have impact every claim needs to be accompanied by illustration/proof. If no proof is forthcoming, then take it with a grain of salt.
I feel the assessment was fair regarding ergonomics but lacking regarding photo quality. Of course as an opinion, no problem, it's interesting.
I believe my 1DX2 blows every camera ever made out of the water (when loaded with gun powder)! And I've been shooting Canon since 1973! However, I'm not a explosives expert, so what do I know.
