I would love to move my Plex server to Jellyfin, but it's not yet at feature parity:

- PlexAmp is a much, much better tool for consuming music than the Jellyfin UI

- Prologue[0] is an app that hooks into your local Plex library to play audiobooks; Jellyfin has no equivalent that I'm aware of

- There's a general dearth of iOS and Android apps that support downloads/offline play that sync play progress back to the server
