It very much depends on the book for me.
Cheap sleazy mystery/sci-fi/fantasy works great in the car for long road trips for me. And sometimes an audio book is just the thing if I'm puttering around the house all day doing chores.
Right now, for a class I've been taking since the pandemic began, I'd "reading" Obama's latest book, which I decided to try as an audiobook, as he himself is the narrator. The book itself is 700+ pages long, and I didn't feel like devoting the time to slog through it, but it's quite nice playing the 30+ hour long narration while doing tasks around the house. He does a great job reading his own words, and his intonation/rhythm/delivery add more interest to what is sometimes quite dry material.
In general for this class I've preferred the Kindle editions of books, as I can easily highlight passages and take notes, and use whichever device I am nearby to make progress.
Also, in general, I've been transitioning to ebooks for most purposes for several years now. Over the past several years I've donated > 8000 volumes of physical books to the local library book sale, and the house is still infested with physical books. I still get the occasional physical book to sit quietly by the fire in my comfy chair with a glass of Scotch with during a storm, somehow the ebook feels out of place in that context.
