This was incredible. It moves faster than Way of Kings, and reveals a tremendous amount of detail about the characters and the world, while still being paced for the marathon that this series will be. There were several points where I couldn't believe what had just happened and had to go back and reread them. Other portions were worthy of reread due to their sheer moments of awesomeness. Then come the closing sections following the climax. Here reside some incredible twists, even beyond those contained in the earlier sections and Interludes. Words of Radiance is at least one step above the greatness that was Way of Kings. Also, everyone needs Herdazians to keep them in line. 
 ***General spoilers and Cosmere nerdiness below*** 
 Sanderson greatly expands our knowledge of Roshar and its magic systems / physics. We see much more of the Nahel bond and how it operates between humans and spren. Here Sanderson invokes parallels with particle physics and relativity, which I suspect will lead to the interstellar travel he has hinted at coming in future Cosmere books. We also get several insights to the Knights Radiant and how their orders functioned. The biggest reveals (view spoiler)[ regarding the true bonding of spren, their becoming shardblades, and the dead spren used to create the "normal" shardblades (hide spoiler)] will have huge ramifications for the society going forward. I fear what that may mean for fabrials as well. 
 The new viewpoints are very enjoyable. I hope that seeing the assassination of Gavilar from different viewpoints becomes a thing. I'm thinking maybe the next will be from either Dalinar ... or perhaps Sadeas. (view spoiler)[Eshonai's (hide spoiler)] sections were both intriguing and heartbreaking. Deception and betrayal run through these books and do not fail to play on our sympathies.
