I don't think it is just how close you are, but what you are doing. When doing engineering projects I still like to see what someone is doing because there tends to be things that they do that aren't discussed and change how things work. You also can learn neat little tricks this way too.

But code, I generally like reading because most of it is abstract and in your head anyways. So I think the best media depends on what you're doing and what type of learner you are.

I'll add that sometimes I read a dozen articles and just don't get it. Then I watch an OCW and everything just clicks. The reverse also happens. Sometimes you just need a different format and/or a different voice. More options only helps.
