Lessons: In Person vs Live Online vs Watching YT Tutorials?

Title Elaboration: Is attending lessons in person the “superior” route, or do you think Online Lessons can be effective? Who are effective online tutors that you suggest?

I, as I assume many of you, have seen tutorials on YouTube on scales, warmups, etc.

Do you think there is any chance that watching tutorials is enough to train yourself, or is live feedback the key?
