Audiobooks are heavily dependent on the reader. In one case, I had an audiobook where the translator was the reader. She is an excellent translator but a poor reader.

Many authors are poor readers of their own work.

They are certainly good while you are on a long drive etc, because they entertain you while doing some another task which you wouldn't be able to do while reading. During lockdown, I could not read due to the constant stress and fear mongering, but I had to walk a lot every day and the audiobooks were a good way to accompany that.
