It is hard to beat the polish that Plex has. I setup Jellyfin to try it out and I couldn't find a client that was smooth or had the polish of the Plex apps. The AppleTV app was close but then I go down the rabbit hole of codec support. Wanted to like Jellyfin but without a nice looking front end it was a non-starter for me. Good news is you can have the side by side and if a time comes it gets parity with Plex I will be happy to change over.
