What are the difference between audiobook listening or reading? Do they have the same benefits? I feel like there'd be a bigger chance to become at master of rhetoric by making my inner voice read the text in my head as opposed to simply listening to it. But I don't know if that's actually the case and internet isn't helping.

And I know retention isn't a benefit unique to reading, it is provably the same if you don't multitask while listening to an audiobook.
