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 don't have the best way to compare it to another true mechanical keyboard, but, to me, it feels a liiiiiiiiiiiiiiiitle harder that I would want, but thats probably because Im used to low profile switches. Need to work on my finger strength!
