I bought the Emby lifetime license about 2 years ago when the plex remote streaming stuff first started getting talked about. It coincided with my server refresh so it ended up working out. I have been really happy with Emby so far.

One thing to note is that music streaming on remote devices is WAY better on plex, Emby behaves more like a mapped network drive running over the internet to a local music player that then forgets your position on pause or when you move away from the remote app/device whereas Plex is actually functional as a modern music player. I keep a local copy of my music library on my phone anyways and okay through Gonemad so it is a non-issue for me but Emby should work better than it does in that case.

Plex also allows/provides “live” tv (with ads) which can be nice if you are into that, and there is the “free” streaming library too which Emby doesn’t offer. I’ll keep plex around for those features but non-of my stuff is/will be hosted on Plex.
