We build 40Plus. The U-value does not differ from a plastic window and is therefore irrelevant.
The windows last longer, are more ecological (since they are largely made of natural materials), look better, and provide a cozier living experience.
The question is whether the price difference is not significant given current building material prices. I can gladly inquire :-)
