My family/friends uses it on TV all they do is scan the qr code on plex and it logs them in and basically keeps them logged in forever. On jellyfin it logs out randomly. I run a dedicated Nas with 40tb half filled with media. I started on jellyfin and switched over to plex and never looked back. Just the fact that half the people in my replies think the main use case is on a Pc tells you everything you need to know. It's perfectly fine for tech literate people for everyone else plex is superior.
