Which way is better to maintain more information?
Always depends on the student and the way their brain is wired. Some people can remember and learn everything they read, som people can remember and learn most everything they hear, some people can remember and learn most everything they write, etc etc.
From a sciencey perspective, I think writing notes is by far the best way to study. It is similar to the concept be\hind the Wilson Method for dylexics. Multi sensory. Your brain has to be physically engaged in learning, as well as visually and auditorily. If you really want to remember the material, write it down and then study it.
