I don't understand what's the debate unless you're assigning some higher value to the written form, like people who think reading makes you more disciplined or a better person than others in some way. If you remove that and realize reading is a form of communication then it doesn't matter how you make it happen. There was a time when stories and knowledge was mostly shared verbally so it's not like reading is "the truest form". Do what you like/works for you.
