I don't use Unibeast, simply because I don't like their piracy rules. They specifically ban piracy on every level, yet run a site dedicated to violating Apples' TOS. Seems a bit ironic doesn't it? Besides, if I wanted to run Sierra, I would just use MacPwn, which is currently the official way to run Sierra on this site.
However, Niresh's Distro offers many features that can't be found elsewhere embedded in the operating system, such as kexts for AMD, Atom, and other laptops/processors. That is why I would like to see a new Niresh Distro for Sierra. If we would like to work with me, I could probably help him out with anything he needed help with.
For the record, I actually was using TonyMac's Unibeast USB for quite some time, but I went back to Yosemite Zone simply because I loathe TonyMac that much!
