For me? Reading it. I only like audiobooks as car entertainment. I find someone else’s voice and inflection to be distracting.

I used to listen to audio books when I commuted 55 minutes one-way. Though I did see in my travels several times people with a book resting in the middle of the steering wheel, open and being read ! ! !

I guess it depends on how much time you have. To read a book requires dedicating time to it. Listening can be done while you do something else, such as drive a car. You can also listen in the dark.

I try to do both. When my eyes are tired I am grateful for the audio books.

It depends very much on the book.
