I think drawing is better because you can express your feelings by drawing maybe sad pictures if your sad, funny pictures if your in the laughing mood and maybe an angry picture meaning that your angry and upset! Writing is not my favorite because expressing too much of your feelings can cause you problems in school like bullying.
As an artist i disagree with you because writing and drawing both allow you to express your emotions but the bullying problem you seem to have also applies to drawing especially if one draws like a family photo or something. I dont understand why you hate the two, i pair them together draw and write! Make a photo-paragraph
