Yeah, I personally haven't had any real issues with jellyfin which sound like they'd be resolved with Plex. My only real complaint are hardware related (DV and HDR conflict, and some audio format issues) but from what I can tell Plex has exactly the same issues since they're related to the hardware I'm running the app on.
The only thing I'd really like would be some kind of windows media center style control so that I could run a windows mini-pc with the windows app (better control, and I believe more codec support) but have the streaming stick remote functionality.
I have tried plex but didn't really see that it was doing anything for me that jellyfin wasn't.
Mostly just wondering if there's something game changing that I'm missing.
