I know everyone loves Jellyfin because it's open-source, but I've used Emby for years after trying all 3 and it's been the easiest set and forget system. I also think the interface is the best but that's subjective.
If you have the time I suggest you try both Emby and Jellyfin and see which suits your needs best.
You should try a few and make up your own mind; like Emby and Jellyfin.
I have all three installed in my cluster, and jump between them now and then to evaluate how they work for me/my family.
For us, after Plex and over time Emby have been a much "better" experience than Jellyfin; in terms of performance/load/transcoding, how features like sub titles or media scanning or whatever to bugs and crashes.
It makes me sad because I really do wanna go with something more open, but I have to use what works at the end of the day.
Yeah, Definately will do. I’ve spent a decade with Plex, built a library and family knows the interface. So if it’s easiest to change some settings, I’ll stay with Plex. If not, I’m going to try JF and emby
My Plex is offline except for Metadata downloads. What does not work on your end? Why do you need an offline Plex? Plex works offline too, you just get no Metadata unless you have it in the folder of the file.
Jellyfin. Just be weary that it's not great in some cases depending on your hardware. A media server is typically a weak workstation PC. I found that Jellyfin does not handle ASS (most common format for Anime) subtitles well, though if you only have SRT subtitles you should be fine.
There are a few other little things that are missing, such as sorting shows by date last episode was added and the clicking on a show button will always start the very first episode available instead of the next un-played episode.
