I've liked the sound of Plex forever but after it taking years for the wife to finally be comfortable finding her way around Kodi I couldn't really try it.

Just last week I fancied a tinker & I'd heard Plex has potentially begun to enshittify so I ended up putting Jellyfin on our htpc just to test it. As well as all the usual groups, it was simple to create additional collections for stuff only the wife wants to see rather than things we'll watch together. Within a day or so she's already flying round it so we've pretty much moved to Jellyfin. It doesnt seem to like IR remote control like Kodi does which is a shame & I'm struggling a little with the live TV aspect which was also very straightforward on Kodi but I havent looked too closely into it yet.

Overall very impressed with Jellyfin.
