Does anybody have (good) experience with learning languages via self-study/online?

I've previously tried Duolingo but didn't really like it, and it's gamification. I could give it another try.

But I don't know if there are any other trustworthy online resources (I don't mind paying fees if it's trustworthy).

I've never been good with learning other languages, so I don't think picking up books will be enough, but it might be the way to go instead of online resources.
