I suspect that graphical/menu input is preferable only for a Goldilocks range of decision tree complexity. Too many options and displaying them all to the user at once is impossible or unhelpful, forcing you to provide a search function (see the Windows Start Menu). Too few options, and the user won't need any prompting to know what choices they have and what keys they can be selected with (eg. Escape vs. Enter).
