I actually returned a book because I couldn’t stand the narrator. Then I listened to her narrate some other books and came to really enjoy her. And I ended up re-purchasing the book I had returned.
For me, if I have a problem with the narrator, I increase the speed to 1.2ish and that usually helps a lot.
I tried using Libby for a while but my library system doesn’t have most of what I’m looking for. I tried Scrib’d and didn’t really like that either. I’ve also used Kobo but the pricing with Audible is better for me especially since they added the Plus catalog.
I also checkout Chirp periodically since they have sales all the time.
