I’m currently a Plex user and access it from Apple TV’s. I find this is a smooth and stable experience that everyone in the house enjoys and is comfortable. I also use PlexAmp on laptops, mobile and CarPlay.
I am interested in Jellyfin and am wondering if I can expect any hurdles or rough edges moving over?
I use Swiftfin on the Apple TV and love it. Great UI and responsive.
It buffers occasionally but not much more than a paid for streaming service.
