In my own house, or just myself. Jellyfin is fine. I haven't spent as much time on it though compared to Plex.
Plex has its own user auth, I don't need to manage that. My friends and family don't have to hit me up for password resets.
It has apps on pretty much every device.
Users can just log in. They don't need to know what server to type in.
Some days, I am tempted to go back to playing eve. Ive got some good memories.
