Gran plots are indeed more accurate around the endpoint than derivative plots, utilize concentration/pH data before the endpoint to determine the endpoint, can be used where a constant slope crosses the x-axis to find the endpoint volume, and are applicable to both polyprotic and monoprotic titration curves.
