Yes, Emby could be considered a competitor to Kodi. Using a dedicated server on your media computer to organize your media may be preferable to allowing Kodi or a MySQL database do it. The content is accessed by using a remote client. Kodi can be an Emby client by using the Emby for Kodi add-on. I think this add-on is compatible with all skins, but some skins are better designed to work with the add-on.

Emby for Kodi works well with DSPlayer but requires path substitution is used for all sources. This is described in the set-up guide.

So, Emby/Plex are server/client applications, while Kodi is best described as a standalone media frontend/server.

I've now tried with only installing Emby repository and just installing Titan as skin, which is working fine for me, so I don't see any advantage for me to install Emby Server.
