I’ve got Jellyfin up and running right now on a DS620Slim NAS and it’s running pretty good so far. I’ve seen a lot of people say they prefer Plex over Jellyfin. What are the main advantages to plex?
I really have only ever used either of them as a DLNA server, but I was recently forced into Jellyfin and find that I like it much better than Plex. It's faster and more reliable on my system, and for my stripped-down needs, it's a perfect fit. I'd say that if Jellyfin is doing the job you need, you've got absolutely no reason to switch.
