I bought an XBOX One as opposed to a PS4 because I'd heard the Plex client was perfect on XBOX -- personally I like game consoles as media players because they play discs and I'd rather have an overpowered rather than underpowered machine.
I ditched Plex when they came out with a FAST [1] service which was thoroughly pizzled [2] for me. I switched to Jellyfin which I struggled with in so many ways, the terrible XBOX client which was a degraded version of the web client was the worse but Jellyfin's poor metadata handling was part of it.
Last summer I spent a lot of time in a room in our rental house where I tried (and failed) to gentle a feral cat and wound up watching a lot of Tubi and came to the conclusion that FAST wasn't so bad and gave Plex another chance when I rebuilt my home server and I can say I'm highly satisfied.
