Cork wall or wood fiberboard?

We are in contact with two different construction companies. We are not sure which wall systems / insulation are better. Both are ecological made of wood, one is wood fiberboard and the other cork. On the outside, we want to plaster. What is your opinion? Wall systems 1 or 2 (see attachment)? Why?

Thanks for all comments.

Both should work. However, a more precise assessment is not possible with the details provided. But remember - it doesn’t depend only on the type of wall - the execution is much more important than the product name. And please don’t forget the topics of roof, windows, connection to the base slab, as well as the topics of interior ceiling, interior walls...
