I can try to answer any questions, but it doesn't seem like the 8bitdo Ultimate software is availible for download yet. Im not big into mechanical keyboards, this is actually my first, so I don't have much direct comparison experience to other keyboards.
but the buttons are big and f u n.
I really wanted this, but they have no software support for Linux, so instead I went with the Lemokey L3. Should be shipping next month.
They never have software for Linux :(
