I have only used Plex very briefly before I moved to try Emby then Jellyfin. Granted I am not a heavy user of a media server - basically no one else in my household uses it, and I don’t have a lot of content, but I do use sonarr / radarr with it.
The moment Plex put me off was when I realized a Plex Pass was needed to add transcoding capability. What are some of the reasons people like Plex better than Jellyfin, other than those who have been using Plex forever and are just too lazy to explore other options?
I use plex pretty much exclusively for Plex HTPC. Neither of the Jellyfin alternatives to it meet my needs from a usability and customizability perspective. Jellyfin MPV Shim comes close, but for some reason it constantly resets the subtitle and audio tracks I have selected for future episodes.
