Well then put it like this, he stands out as narcissistic from a bunch of narcissists. If you read his biography you'll notice that literally everyone who has worked with him criticised him for it. I understand that you have to be highly confident and even arrogant at times if you want to run a country but with Schmidt it was far beyond that. His one-sided rivalry with Willy Brandt especially makes him look bad, decades after his death and he was still taking cheap shots at him, talking about how he had no clue about the economy etc.
He also switched his standpoints pretty often to the complete opposite and back especially in his old age, although looking at other 80+ year old statesmen you could say that's not really a distinct characteristic of his.
