I haven't read Speed of Dark. It looks preachy, in a way that wouldn't allow me to reminisce about playing lawful good characters.

Scarring is perhaps a little strong, and I read Architecture a very long time ago. I remember that it was confusing, and that it featured a number of intentionally repulsive descriptions of breast-feeding, and that it had an unsatisfyingly unhappy ending. I read Grunts anyway, though, because really, how could you not?
