All input devices take practice to operate well. They also have different ceilings. A touch screen is fine for viewing things, but the ceiling for text input is very low; no matter how much you practice you will never be very effective at it. With a keyboard, however, the ceiling is much higher. I don't have much experience with a game controller, but I would say that they are better than a touchscreen. They still get beaten by a keyboard plus mouse, even if most games don't need the full keyboard.
