I’m a long time Linux user 20 years or so and have tried loads of distros in that time. Eventually I got fed up and settled on Mint for quite a few years, but about 6 months ago an old colleague told me about Zorin as he was impressed with how it felt ‘proper’ from a user perspective. I tried it and actually liked it so much I fully switched to it as my main OS. It’s got all the user friendliness for when you just want to use it for work tasks, but still everything else underneath for when you want to experiment etc.

Honestly it just works and works well. I had all sorts of issues with Plex with subtitles not working and weird transcoding issues where red blocks would randomly appear. Also I found Plex kinda ugly tbh. I tried Jellyfin and it seemed a bit ‘hacky’ but this was a few years ago so maybe it’s improved but I currently have no reason to try it again. If you’re using Plex/Jellyfin/Emby you are most likely pirating media so worrying about GPL violations is probably not top of the list.

Try Emby. It’s a more polished Jellyfin although it’s not FOSS I find it much better than Plex
