Proffie:
Open source soundboard capable of smooth swing fonts to give you the complete experience, it has fully customizable blades using online editors and can have any effect you want to have on a blade, it has to be programmed by Arduino which makes it more difficult to add fonts and blade styles but once you get the hang of it the possibilities are endless. Its also easier to use compared to CFX as it has a basic 2 button activation and aux but can also have full one button support without compromise.
CFX:
Closed soundboard capable of smooth swing but is fully user upgradable through the SD card, though it can be difficult to get everything up and running as there are many settings to configure, the interface on the saber has more of as learning curve than proffie as you need to go into font select menus and music payer menus to be able to navigate the saber.
Verso:
Entry level closed soundboard capable of smooth swing and basic blade profiles, fully user configurable and probably the easiest out of the bunch to get up and running, has 2 and 1 button support foe basic functions. It has new features coming that the user can upgrade via the SD card which makes this a perfect entry level saber.
