I know Raspberry Pi has a huge community (that is a huge benefit). My last 2 Kodi install have have been with R-Pi 2 (retropi) & 3 (libreelec) respectively. I found both to be kind of clunky and on-going buffering issues (my internet connection isn’t all that great).
While looking to do a new build I started researching alternative Single Board Computer (SBC) options. There seems to be many with a significant amount of additional options and computing power.
