[Cosmere + SP3] Thoughts on the book?

One of my favorite Sanderson books period. In fact, while I don't want to state it too definitively because recency bias is real, I think this may very well be his best individual book to date (it's hard to fairly compare a series to a single novel though). Everything about it was so well-done, I wish I knew more about the behind-the-scenes of storytelling so I could compliment it properly.
