Love it all, but each for different reasons.

Corwin's Saga (books 1-5) is lovely. I love it mostly for the way the author describes scenery "Walking Shadow", or various spiritual journeys. It feels like he knows something about the kind of High Weird spiritual practices like meditation practice and, let's face it (it was the 1970s!) - psychedelics, show. The plot itself is not that interesting, but it kept my attention. The conversations were a bit weird, as in that no one had their own way of speaking. Not sure I can describe it. A bit like how all bible characters speak in the same way.

The second (last) series (books 6-10) feels more like real people talking, and there is more plot, but less spiritual and Shadow Walking descriptions.
