I tried to switch from plex to jellyfin 2 months ago, running both at the same time in containers, but I removed jellyfin after a week
The main issue was the CPU usage, on idle Jellyfin was using about 1vcore while plex used only 0.3, no background tasks seemed to be running and after a week my 4tb of media should have been indexed
Also a feature that I use regularly with plexamp, starting a radio from a song, was not giving me good results on finamp
