Currently just using Jellyfin, but have used both Plex and Emby in the past.

Main reason I switched from Plex was mobile support. I also prefer FinAmp, which I use to download music for access when I’m at work, and at home I can access my entire collection through the same app.

I recommend setting up everything through Docker. I have Portainer running, which helps manage the containers. It was pretty trivial to switch what I was using by just setting up a different container. You can also have both running at the same time off the same library, and see what you prefer.

Yeah, I switched to Jellyfin ages ago and never looked back. Haven’t really run into anything I’d want to do that Jellyfin can’t do but Plex can.
