Jellyfin continues to be a noticeable downgrade from Plex, but it is chugging along to being as good. If you're already a Plex lifetime subscriber the only logical move is to make sure your library is setup in a way that is compatible with both. There is no reason yet to switch away from Plex, unless you've had that terrible UI forced on you on Roku. I can switch at any moment when ever some MBA decides to enshittify something important.

I have no idea who will ever buy a lifetime pass at 10x what I paid for Plex in 2019. I struggled with the decision to pay $75 back then. There were effectively zero competitors to their product then.
