Does it require, e.g., more attention or whatever?
I'd say listening requires far more attention. If you miss a bit when
listening, you have to somehow rewind and listen to it again.
Rewinding is usually quite imprecise. When reading, you are in
complete control and it is largely impossible to miss a bit (although
I'm sure we've all experienced the annoyance of reaching the end of a
paragraph and realising you weren't paying any attention and having to
go back - it happens much less often than with listening, though).
