Reading through the third book right now, and either missed or completely forgot the suggestion to try not to follow it, but glad I saw this message because I am often getting confused as to where people are. Still having a blast though! Well written books? Maybe not, but they are very fun.
So far DCC is giving me a nice break from the Cosmere and Sanderson's in depth world building.
Everyone usually recommends Mistborn as the entry point. I personally started with the Stormlight Archive (The Way of Kings).
His writing generally gets better with each book, after going from The Stormlight Archive (all the way up to Rhythms of War) and then going over to Mistborn, I noticed a bit of a difference in his writing.
If I were to start all over again, I would go with Mistborn. I thought this flow chart someone made on Reddit to be pretty good.
