Heads up! Plex media server with the Plex clients on all your devices is such a smooth experience. Highly recommended. And their “Watch together” feature is so nice for people that prefer to stay in bed and spend the winter binge watching next to a warm body.
libreelec is so rad. I hooked it to my van's screen, gave my kids a PlayStation remote, and drove halfway across the country while they were able to watch all their favorite shows and movies.
Just started my switch last weekend! Jellyfin is amazing so far. Just need to figure out how to export all the Plex metadata and posters to .nfo files.
I’ve been searching all over and haven’t found anything yet. The only answer seems to be to directly open up the Plex database in sqllite and navigate the schema myself and figure out how to export the specific tables and fields I want in some usable format. Once I have that, there are tools to generate .nfo files. 
Oh, I meant browse to the webpage like you would on a computer. Is there not a browser available? I've only got dumb tvs, so sorry I can't be of more help.
So it has a dedicated music app?
It has music filtering?
Good 4k/x265 performance?
Has a third party (or built in) utility that shows me streaming usage?
Allows me to limit remote users to streaming from a single IP address at a time?
Let’s me watch something together with another remote user?
Has an app for most any device (like Plex or Emby) that does NOT require sideloading?
Has built in native DVR steaming/recording support?
And they recently added a feature where they tell your friends on the platform what kind of porn you've been watching ✌🏾
I think I'll stick to Jellyfin.
Don't feel bad. Plex is working wonders for me. Yea, there are things that annoy me about it, like the volume issues. But all in all, it passes the "wife test".
99.9% of the people here who trip over themselves to shit on Plex and recommend any other service that requires IT knowledge to consistently and easily give access to family members, don't have to deal with the "wife test". Substitute "wife" with husband or mom, or grandma.
