I really, really wish this discussion on his writing style that I ended up having with Sanderson himself on Westeros around 10 years ago hadn't been deleted in a board purge, because it was an interesting discussion of style (if I recall, he argued that he was purposely aiming for an "invisible" style that would enable him to focus more on establishing the action and allowing readers to insert themselves in the characters' roles). I disagreed with him, but it was a fairly productive discussion.

That being said, his approach toward writing just does not appeal to me. But then again, while I like Martin's stories better, I wouldn't claim him to be a good stylist either. As for SF/F writers that do have interesting styles, I suppose most of my favorites are those who "crossover" into other literary genres. Certainly not the ones you mentioned
