Just finished Oathbrigner the other day. While good, I was left disappointed as it's not nearly as great as the first two. It seems to suffer from being a "middle book" and there were far too many PoVs at the climax IMO.
It also doesn't help that my boy Kaladin [SPOILER - highlight to read]: was basically irrelevant for the last two parts of the book.
So good book over all, but not nearly to the level of the first 2.
