The main difference I see is that when a professional wants to read something very thoroughly, they employ techniques of what's called slow reading. That's usually when the highlighter comes out along with note-taking materials.
This is possible with print information because of how much of it is put in front of your eyes at once. Rereading a paragraph, even a half dozen times to guarantee you fully understood it, is very easy with print. It is not with audio. Flipping back to page xxx to check something, also very easy with print and less so with audio. Smoothly speeding up/slowing down your rate of consumption to match the complexity of the current topic, also easier with text than audio. Etc etc.
So, for casual consumption, they're fairly equivalent and both fine. But if you wanted to claim mastery of a complex topic after putting years of intensive effort in, I'd say that probably required some reading that could not have been replaced by listening, and if you did no reading, I'm going to be a little doubtful of your mastery of the knowledge. It's possible to still understand what you need to, of course, but you definitely neglected what is usually the most efficient, reliable method by far.
Yeah that's more of a hotel thing. I'm guessing this is that influencer trick of intentionally lying about a detail so people will make comments to correct you, giving you free engagement.
