I disagree. While books might be more imaginative, as you can read the lines the way you like, most of the times, at least in fiction, the emotions are written out. Oftentimes, because of that I need to go back because I read the paragraph "wrong". And that's just one part of the imaginative experience. While listening to an audiobook the way you see the setting, the characters and their actions is still entirely up to you. It's fine that you, personally, prefer books. But that doesn't make audiobooks bad.
