This is legit the opposite of my experience. I am a relatively tech savvy user, I like to fiddle with all the settings and an ugly UI doesn’t inherently deter me as long as the experience is good, so when I first installed jellyfin I was ready to have a clunky experience fighting the UI.

Despite that, I was legitimately surprised at how Jellyfin was far less confusing for me to use out of the box than plex ever was. I found Plex’s UI very confusing to navigate on my TV and my family did not like using it either. I remember especially hating all the extra categories and freemium content plex added that I wasn’t interested in viewing but couldn’t remove (or at least did not find a way to remove). In Jellyfin all of my content is just there and very easily categorized and there’s no superfluous elements in the UI, just my stuff that I want to watch.

I remember plex also gave me more trouble during installation than jellyfin did. I actually found jellyfin very pleasant and intuitive to setup. Plex sent me down a Google rabbit hole to diagnose why it wouldn’t boot at all.

It was genuinely such an awful experience as a first-time user that it made me wonder why anyone would use plex.

Just to add on to this, in those unfortunate cases where there really is only Fandom, you can use an extension like LibRedirect which will redirect any Fandom pages to a breezewiki instance, which is a stripped down, privacy respecting, no BS front end for Fandom.
