Reddit mentions of The Tales of the Otori Trilogy: "Across the Nightingale Floor" , "Grass for His Pillow" , "Brilliance of the Moon"

I would first echo most people here and say Sanderson's anything- Elantris comes to mind as a good recommendation.

When you say in the same calibre, are you talking in terms of story, in terms of being high fiction, in terms of length or in terms of moments that make you go, "ohhh... well DAMN!"

I would recommend a lot of things I saw below, so I'm going to try to not do that any more than I already have. The Conan Chronicles by Robert Howard are fun and a much unappreciated classic of Low Fantasy. Orcs by Stan Nicholls is a great series, somewhere in the middle ground between high and low fantasy, and does an interesting twist on the classical fantasy story. The Gentleman Bastards series is another interesting take, but it is more of an Ocean's 11 in a fantasy world. I only saw one mention, but anything Tolkien is a must read if for nothing else than to pay respect to the godfather. The Night Angel Trilogy by Brent Weeks is another good story, and it uses a lot of the ideas Jordan uses in terms of who knows what, why and when to progress the story. Finally, for a more Eastern themed book, Tales of the Otori by Liam Hearn is a good trilogy with a lot of political twists.

EDIT: added a link for Elantris
