> XBMC is a player. Plex is a player, sure, but it's also a server. It transcodes your media and hands it off to other Plex clients, and more importantly it serves metadata to Plex clients so that they don't have to fetch and store it locally â" the main weakness of XBMC in an environment with more than one player,
Not a big deal really.
XBMC is the gold standard when it comes to metadata management. So the fact that you have to do it n+1 times is really not a problem.
The lack of a central repository means that you can't do cool multi-room stuff. However, I am not sure that Plex does any of that either. Meanwhile, it's central metadata server is an unbelievable pig and resource hog. It's an amazing disaster to behold.
The main value of Plex is that it will accommodate that $60 streamer that has crap hardware that can't really decode anything.
