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.
I cannot fathom why, but people do not seem capable of understanding resolution, screen size and viewing distance as important factors that interplay with each other.
8k is absolutely pointless on a 49" TV that is several metres away. However, I will take 4k over 1080 on even a 24" computer screen every time.
That is just me though, your preferences and vision may be different to mine. Same with the monitors. You like multiple screens, I prefer a single larger screen.
2 problems this week
Accidentally had 2 Jellyfin pods trying to write to SQLite together and corrupted the DB. Not really anyway to fix it so just killed it and rebuilt the library.
Also, my son's Minecraft server got corrupted. Longhorn backup to the rescue ๐
