The big difference (aside from port count) between the PACDrive and LEDWiz is that the LEDWiz has the ability to set a variable intensity (0-48) for each port. For single color LEDs this allows you to set how bright they light up. For RGBs, the intensity is used to set a wide range of colors. You can use a PACDrive with RGBs but you'll only be able to set 7 colors; R, G, B, RG, RB, GB, RGB.
