I want to like Jellyfin. I've been running it in parallel with Plex for at least 3 or 4 years. It doesn't work well most of the time for me though - mostly client-side issues like bad rendering, issues with subtitles, videos hanging during seek, many others... I could live with some of the issues I've found but every time I hop on JF I run back to Plex. As much as I hate some things Plex have been doing and the lack of troubleshootability when things go wrong, it mostly works most of the time. JF mostly doesn't work most of the time (again, for me - it seems it's excellent for a lot of people!).
Well yes, Jellyfin works well enough for me: installed on a NAS via Docker, accessed from desktops, Android and iOS devices, without issue.
It does seem a little fragile at times and some things are annoying (managing playlists in particular). But the way Plex does business is not acceptable to me, so I didn't even try to install it.
