It all comes down to how each input mechanism affects your ability to turn. On a console, the angle in which a player can turn is a function of both time and displacement of the thumb stick. No matter how far players want to turn, they have to pay a time cost. Even at the highest controller sensitivity, there is a time cost to be paid.
