I don't understand why anyone continues to give Plex the time of day. Jellyfin has far and away eclipsed them.
Because I bought a lifetime pass a very long time ago, and their apps across all platforms look and work consistently. I only recently switched to Jellyfin because Hetzner blocks Plex, but otherwise I wouldn't have had a big reason to switch.
I went with Plex AV few years ago for two major reasons:
* a native Xbox app (I believe Jellyfin may now have one)
* non-techie acceptance (Plex seemed more polished at the time, will need to reassess now)
Either way, I'll be warning my spouse that things may be changing soon.
Do you have external users (outside your network)? My understanding (and the last time I tried) is that Jellyfin lacks in this department quite a bit. That and ubiquitous clients.
Plex client is available almost everywhere and overall, Plex mostly "just works". The latest Apple TV client changes have me hot and there are things I don't love but that's what's kept me in the Plex ecosystem. I am looking around now though since I'm so disappointed with the new clients/UI.
