Digital Filter Design using MATLAB filterDesigner Tool and GUI

This brief 10-minute multi-band filter design example video shows how to use MATLAB filterDesigner Tool and graphical interface to design a digital FIR filter that satisfies a demanding multiband filter specification that has three stopbands and three passbands with multi levels as shown. There is an alternative way to design this filter directly using Matlab firpmord and firpm functions that are effectively the Park-McClellan equiripple filter design algorithm used also by this GUI. Which method do you prefer? Using this comprehensive GUI or using the firpm functions in MATLAB?
