Both applications are good. But most likely I really preferred to use YouTube. YouTube is more knowledgeable compare to Netflix. It contains a lot of tutorial, documentaries, explanation, history and etc. Also, YouTube is very convenient and FREE. I consider YouTube also as EVERYONE'S TEACHER. You don't need to read books or search the process on Google. Kindly click the search button and type the words. And for a moment you will see a video explaining how.
