I haven’t read sword of truth and I actually started reading because I am a Sanderson fan. But they are good. A bit slow to be honest, and apparently it will get even slower, but the world is fucking awesome. The world is set in an age which lasted for 3000 years, and there are significant things that lead to the creation of this age and Robert Jordan makes it feel like so. The world has a deep fucking history.
There is a part in book 4 where the main character gets to know events of the past (This is the best I can say without spoilers) and that had me in tears man. I would tell you to read upto there at least, then decide. I know it’s a long journey but I am loving it.
