When I had to decide between Plex and Jellyfin, I noticed that with Plex it was mandatory to have an account even when self-hosting (!) so I'm not sure whether it's better or worse than Jellyfin, I just didn't bother trying it out because of that.

I was camping without service last year. I wanted to watch some House MD I had downloaded in the plex app before I left. I fire up plex ...it can't connect. Why does it need to connect? Bye Plex. Hello Jellyfin.

Plex is aimed for a simple ease-of-use experience, so if you aren't technical enough to setup a reverse proxy, Plex offers all the authentication and proxying for you.

It's not a true self-hosted software. It just depends on what matters most to you.
