Everyone learns better with a teacher because no matter how you think you learn best, getting feedback from someone who actually knows what they are talking about is required.

It depends on the matter, purely technical & learning subjects is fine.

On personal & spiritual development it's very useful.

You can learn most things on your own and be "fine." But having a teacher accelerates your rate of learning beyond that.
