My parents are getting a new tv, and are asking for recommendation. I think all I can influence is the brand/model (not realistic to propose rpi and more complex systems). I instinctively avoid google/android and lean towards anything else open source, so probably LG WebOS… But I had bad luck searching for more detailed comparisons. Maybe you have experience or opinions?
Its good if everything you need can run from Kodi. It uses its own Linux distribution in the background, so you won’t really be able to install anything else unless you build it.
Then run it in a container under a better distribution if you desperately need to put neofetch on your HTPC. Or run the other distro in a container under libreelec since I’m pretty sure it supports them.
