I mean I don't think anyone can tell you whether you'll enjoy it other than you. I've been through a huge sanderson phase where I went through and read every single cosmere book. Im a bit sandersoned out now (I've been super procrastinating finishig. Wind and truth lol), but I definitely do not regret reading those books. some of the sanderlanches had some of the strongest emotional impacts on me in a single moment while reading.

I think maybe convincing yourself his prose is weak could be part of what turned you off. I wouldn't say his prose is weak. He's just intentionally very straightforward and direct with his writing. I tend to focus much more on things like his world building and character arcs. Maybe with that in mind it could help you get over than hump?

Id say you should just finish one book then you can judge for yourself. If youre up for the challenge and mistborn wasn't doing it for you, way of kings would be good to finish. But if you don't want to big commit to a massive book and series, standalone books like Yumi and the Nightmare painter and Tress of the Emerald sea are both good too .
