How would you rate his performance as a leader and tactician?
Haven't we already been here before?
In any case, technology aside the Mongol army, society and state(s) of the XII & XIII centuries may well have been the most efficient military machine ever; by any measure, Ain Jalut was an unparalleled deed relative to any other defensive victory I'm aware of.
Far as I can tell, Baibars must be held personally responsible for both this victory and the eventual inability of the Mongols for achieving the expected retribution.
