Jellyfin is what I use now. I was using Plex for the longest time, but I personally feel like they keep moving away from their roots so I ditched them for Jellyfin for about 2 years now and it’s been great I haven’t looked back. I still run Plex, but it’s for a few of my users that refuse to move off it 🤣
I use whatever is cheapest at the time of buying. I just make sure they’re not SMR.
