I take it you haven't read The Children of Hurin. It really has no comparison to the rest of Tolkien's work. Compared to the other books and collections, it feels like a John Grisham novel.
I realize this is subjective, but I didn't get that feel at all from The Children of Hurin. I thought it did a pretty good job of capturing Tolkien's style (and, of course, significant passages were taken verbatim, or nearly so, from the shorter versions in The Silmarillion and Unfinished Tales).
