I don't think I've seen any author that nails pacing and build up as consistently as Sanderson. All of his books are this steady build to a climax that never fails to be the most awesome shit ever. The climax of Hero of Ages was probably my favourite, because there's so many "holy shit" revelations and awesome heroic moments for pretty much every character. I think what makes it work is that all the revelations and twists make sense from the crazy internal logic his worlds and magic systems have. So much so that if you're paying attention you can actually figure some of it out.
Hero of Ages (Mistborn 3) spoilers: For example, I was able to predict that Vin's earring was what held back her powers well before the moment Marsh figures it out.
