One thing normal notation is great for is hand writing score during composition. The filled in quavers become a diagonal line (running bottom left to top right). Whole notes a little circle. And the rhythms and slurs are easy to draw. In fact I think this is why classical notation is how it is. In medieval times the scores would have been hand written. I would hate to handwrite with this during composition.
