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.
https://github.com/nova-video-player/aos-AVP/releases
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.
Definitely Plex, it’s pretty much the entire reason I’m self hosting in the first place!
Haven’t watched or listened to any mainstream media in another way for years and it also gets plenty of usage from other people.
