A lot of people love Jellyfin, and it’s very clean and works well, but I find that a lot of media types don’t work. I never have any problems with kodi and all sorts of video media, but it’s definitely more bloated than jellyfin. Kodi just works but Jellyfin seems cleaner with the occasional format issue.

Family used plex cause that’s the easiest, but lots of concerns about the way the company is going and privacy. It doesn’t bother me but you should read about it.
