We have both.

Kodi use Jellyfin for its media library and Kodi is excellent for a lot of the TV we watch. catch Up TV has replaced the decoder for watching terrestrial TV.

One thing that sucks in Kodi though is Arte (a franco-german channel that is a leans towards “intellectual”). For that, the LG WebOS app is much better than the Kodi add-on. Other than that 1 app, we could happily plug Kodi into digital signage panel if they weren’t stupidly expensive.
