Server wise they are practically identical, but the AndroidTV app of jellyfin lags behind quite a bit, the media player is bad, it doesn’t handle well changing subtitles, moving the clip forward and backward… Some of these are fixed by using an external video player, but weirdly enough there have been some movie formats that jellyfin couldn’t handle (the TV app) and emby did.

I just wish that the TV app were identical to the android app with remote functionality, but I’m no android dev so I’ll stay put and wait.
