What do you think makes a book better or worse suited for audio formats compared to regular reading? (Assume one reader, not a full cast)

I've said this before here and there, but once again I saw this come up in another thread and it got me wondering on a broader scale. I've seen many people talking about how they had to DNF the audio book of The Count of Monte Cristo because it just felt like far too much to keep track of, and that made it difficult to stay interested.

Now before I go too far, while I loved Monte Cristo myself, I'm fully aware that there are plenty of people who DNF (or simply dislike) this book when reading with their eyes as well, often for the same reasons as I listed above. This thread is less about whether you do/don't like Monte Cristo, and is more about what makes books more or less easy to appreciate in audio format. Monte Cristo is just the example at hand which I'll use for my own points, because I think this book suffers more in the audio format than it does from traditional reading.

I also don't claim to speak for anybody else here! This is just what does/doesn't work for me, and I'm interested to hear what others have to say.

I'll fully admit that I already struggle with audio books to begin with. Not because I consider it to be less-than or anything, I'm just very much so NOT an audio learner, and have a difficult time stay focused on something when audio cues are my ONLY input for it. Nevertheless, there are a couple of things about Monte Cristo that strike me as something that might be tougher to keep a mental map of.

1. Characters. There are a lot of characters in Monte Cristo, and I know for sure that I'd struggle to keep a good grasp on who each character is and what their role in the story is. I think personally I have a bit of a pattern recognition thing where actually seeing names in front of me makes it far easier to ingrain the character into my memory bank for the future. Likewise with a movie/show when there are faces, it provides a visual input to contribute to the mental map, unlike audio.

2. Ease of rereading passages/scenes. Sometimes it's nice to go back and make sure you caught something properly. For me personally, I'd have a much harder time justifying a rewind on an audio book because I'd feel too troubled to go through and hit rewind on whatever I'm using to listen. It may just be one extra step, or maybe it's three, but it would feel (to me) not worth the effort, and I'd just power through anyway.

3. This one especially is a me thing, but visualization. Personally, if I want to take the time to truly visualize a setting or a character description, I don't mind taking a moment to do so. With standard reading, I can just pause whenever I want to do that, whereas with audio books I would need to hit a pause button. It sounds silly, but this absolutely would distract me far more than it's worth. It would make the audio experience feel far more clunky in comparison for me.

I've rambled long enough. I'm especially interested in hearing from those of you who enjoy both audio books and standard reading! Can you tell in advance how conducive a book will be for one format vs the other? Are there any examples of books you actively disliked in one format, but really enjoyed in the other?
