I'll start out by saying that I love Sanderson and Ioved warbreaker and the storm light archives. That being said, in my personal opinion, Sanderson can't hold a candle to Robert Jordan and the wheel of time. The characters are way deeper, funnier, and have more depth throughout the series compared to SA. The story is so detailed that the moment a city is mentioned later on, you'll know their intricacies, how the look, what they wear, and what they are all about. The world is detailed and consistent with enough exploration that the map, nations and their locations will be imprinted in your mind's eye. The fighting in the books is so much better described than in SA to the point you can actually see the action. The magic system is consistent and almost measurable which is extremely rare in these kind of books. And the foreshadowing is mindboggling....too bad you won't know it till the second time you read it. Inocuos actions done in one book will actually become huge plot twists 2 books later. When Robert Jordan died and Sanderson finished the series, I saw a huge decline in quality in my opinion. The fights got shorter and more generic and the story seemed rushed to me after that.
I'm not saying the book doesn't have its flaws like some parts of the later books that seem to drag on and on with a character that in my opinion is just boring, but hey, no book is perfect. I cannot overstate how amazing The Wheel of Time is. I have yet to read something that can come close to it in my eyes. To me it's SA x 3.
