Spin-offs that don’t ruin Frank Herbert’s established canon

So it seems that the majority of people online seem to dislike pretty much all of Brian Herbert and Kevin J Anderson’s books for various different reasons, the main of which seems to be that they aren’t written in the same style that Frank did and that they lack the complex themes that made his books so great.

Many people consider Brian work not canon and that’s fine, I personally want to attempt to read some of his work because I am interesting in learning more about the Dune universe.

Are there any books by Brian that don’t contradict Frank’s original work and lore?
