Hi SP,
I'm not sure if they like to see advertising for other OSes in this board. During the last years I tried different OSes like libreelec, openelec and coreelec on Pi2, PI3 and C2. They all have their pros ans cons. In my case (HD-Audio Setup with Atmos and DTS:X) the C2 in combination with CE works best, but I am missing the Full 3D MVC support. And I was not able to move my Hyperion Setup from RPI to C2. Because of this I am using both, C2 and RPI.
