I love Brandon Sanderson's books! He always has such interesting magical systems and the stories are great. It took me a little while to get used to his style of not explaining everything at once (What's a spren, for crying out loud???)

But after you get used to that storytelling quirk he's an outstanding author. You just have to trust that he'll get around to explaining undefined terms later on. Much of his writing has been bought for movie rights recently, so I'm really looking forward to those. It'll be awesome!
I didn't enjoy his juvenile books as much. (Are they called young adult books nowadays?) And there are a couple of standalone novels that I could have lived without having experienced- but on the whole his work is really good and he's very prolific. That's very nice to have in one of my favorite authors. Several books per year, unless he's working on one of the huge ones. Not like Patrick Rothfuss who puts out one or two a decade.
I've actually been considering going through the Wheel of Time series, just to get to the book he wrote.

I bogged down on the first book of that series a long time ago, so I've never read the Wheel of Time.
If you liked (but don't actually remember) the first Mistborn series, Alatar, you'll probably like the books after that. They are set several centuries after the first set of books with a new set of characters, but they are still quite entertaining. I've been through both a couple of times and still can't decide which era I like better.
We just finished Sanderson's latest book "Skyward" and while it didn't have magic, being more of a science fiction tale, it still had all the elements of good story telling that we've come to expect and he managed to surprise us several times with plot twists that in retrospect made sense, but we sure didn't see them coming! All of his books are like that. Unpredictability is what I value most in authors, I think, and Sanderson never disappoints in that respect.
