Honestly, due to my perpetual difficulty with writing both neatly enough to read and quickly enough to keep up with my thoughts (it's always been an either/or thing), I feel much smarter when typing (on a physical keyboard; I also can't type that quickly on a phone keyboard). Adding in the ability to arbitrarily jump around and edit stuff, I feel like I can always express myself in a way I'm happier with at a computer than on paper.
