To each their own. However, I’ve read all of Brandon Sanderson’s books and I can definitively say that the writing style changes between Mistborn and other novels that are more recent are massive. Mistborn was good but it was his first published book. The more recent releases are a bit more easy to read. Tress even has a dragon in it. However if you’re not interested at all, try reading the Dresden Files by Jim Butcher. It’s great magic fantasy set on Earth. However a similar warning applies - the first few books are a bit of a slog. If you read these, maybe start on book 3 - the first two aren’t as story centric.
