It’s really hard to compare (nearly complete) series with a standalone book.

Maybe try Mistborn: The Final Empire, and just read that specific entry of the Mistborn series and ignore all the other Cosmere books.

Unfortunately I’m not very good an answering this question, because I often go for long running fantasy series and not one off books.

I’m assuming you’re looking for something in the realm of high fantasy, right? Or are you genre-flexible?
