IDK, I couldn't finish Wise Man's Fear, finding it to be a little too show-offy on the author's part, while featuring too many magic-school tropes and skipping the more interesting things alluded to in the narrator's life. I couldn't get much more than a couple of chapters into Mistborn, so you've already show more perseverance than I.

Some of my favorite series include
WoT, of course,

The Dresden Files by Jim Butcher (which shows some fairly dramatic improvement in the author's writing quality as the series progresses, though I could not get into his more traditional fantasy series, the Codex Alera),

Martin's Song of Ice & Fire, which is the most WoT-like series I've encountered in terms of style, scope and world-building detail.

Erickson's Malazan Book of the Fallen was good, but frustrating to a casual reader, and I never finished the last three or so books.

Jacqueline Carey wrote a neat two book series that was sort of an analog of Lord of the Rings, but from the PoV of the villains, but she's better known for her "Kushiel" series, starting with Kushiel's Dart, which is a neat story of intrigue set in a kind of fantasy alternate Europe, but whose mythology and primary society is completely ridiculous upon close examination. The story is interesting and the heroine kind of appealing, whose shortcomings are lampshaded enough that it can be tolerated.

Robin Hobb's Farseer trilogy and its sequel trilogy were very good, but I didn't really like the other books set in that same world, as it seemed to me that the author was much more interested in the things about that world that interested me the least.

I hated the Harry Potter series.

I perversely like the Sword of Truth series, despite the appalling writing (worse than anyone on this list, including Sanderson), and some serious philosophical disagreements with the themes and moral code of the series. I have not bothered with the sequels to the main series though, having read only the Omen Machine and not finding it sufficiently engrossing to bother with the subsequent book.

I love Conan the Barbarian, having read everything Howard or Jordan wrote on the character, as well as a bunch of pastiches by several other authors.

I really liked LE Modesitt's "Recluse" Series and the Corean Chronicles.

I read several of David Gemmel's Drenai series, and found them very much to my taste.

Glen Cook's Black Company series was also very good.

I also liked the Discworld by Pratchett, up until the last hal dozen or so books.
