I honestly gave jellyfin a try but it didn't work for me for several reasons. The server wouldn't find some shows or movies no matter what I did, and I had countless issues with subtitles.

I'd recommend giving jellyfin a try because it's a worthy project, but it's not even a competition, Plex is hands down much more user friendly, if you can excuse the fact that it's closed source.

Now for findability I can't recommend Kagi enough. You can find virtually anything there, no filters and no bullshit results.
