Topic per title, basically.
For me: after setting up all the integrations and fall overs using the arr stack and Jellyfin (inc Sabnzdb etc)… I keep circling back to Nova video player.

It’s arguably not even self hosting…but there something undeniably cool about sticking a USB stick into a router, installing a single app on your TV and boom, done. EDIT: of course, it can consume the *arr stack, integrate with Ombi etc
IOW, I really like stuff that simple to set up and punches above its weight class.
XMPP is nice but even with all of the quality of life extensions it definitely feels clunky. I tried switching to it recently from matrix and while matrix leaves a lot to be desired I found it was more useful in its current form than XMPP.
