Do you consider these buildings to be "the best in the world"?
I think the point is sometimes architects eschew local traditions or materials to make a building to their aesthetic standards, often to the detriment of the buildings inhabitants.
These houses might not be "the best" (how would you even classify that?) but they are "evolved" to be comfortable and efficient in the areas in which you'd find them.
Read A Place of My Own by Michael Pollan for an exploration of this very topic.
