I've been using plex for a long time and have dabbled in Emby on and off for the last few years - I'm becoming more and more annoyed with the direction that Plex is heading, so I'm looking to drop it and migrate to Emby.
One of the things I use a fair bit in Plex is the ability to sync content offline, and then play that synced content on a TV. I travel a lot with work, and normally travel with a FireTV stick. If I end up in a hotel with sucky internet, Plex allows you to use the mobile device as a local server, so you can browse and playback the content you have synced from another local device like a fire stick, or cast the local copy to a chromecast.
I've seen that Emby has 'Play On' options via the cast icon, but a lot of the time it doesn't want to do anything (especially when you are browsing downloaded content). When it does work, it's streaming from the server, not the mobile device.
Are there any native options for 'offline' playback of synced content on another device, or am I asking for something that doesn't exist?
