What is the best fantasy you have read in terms of quality of prose?

Fantasy has always been a genre near and dear to my heart, but I've come to realize in the past few years that a lot of fantasy is poorly written, at least stylistically. The bulk of its canon falls so easily into tropes, cheap writing, corny characters, and conflict between worldbuilding and narrative. Given how closely linked Science Fiction and Fantasy, it seems like both genres encounter similar problems, but I find that even SF as a genre features more high-quality prose.

What are some fantasy books you all consider to be both excellent representations of the genre and quality prose?

Personally, I just re-read A Wizard of Earthsea and, as always, Le Guin never fails to awe me, so much so that I ordered the three sequels (which I have not read) to dive more deeply into her fantasy prose.
