We'll obviously call it SHITFAÇFW, the Super High-tech Ingenious Thing Freaking Awesome Custom Firmware.
I would go on the side of karl3ds if it were open source because they are more advanced than oska and the devs are way more numerous and active
only problem is the homebrews and the fact that I would like to install my cartridge on the emunand ^^
but after it would allow piracy sooooo.
