ive been using kodi (xbmc was better moniker) since google killed sagetv. i recall attempting plex, but it seemed to lack some open/extensibility (its been awhile).
i have a side project i want to make as a modular plugin generating a cable layout with original air orders and networks/channels… kodi seems most optimal, but ill admit its been a long while since i looked at plex.
so why plex over kodi?
One of the things that really put me off Kodi (as a long time user as well, I also had an XBMC xbox) was the mentality of “it shouldn’t be easy, there shouldn’t be any setup wizards. It needs to be difficult to configure and get working because we’re l33t haxors!” in so many kodi forums and affiliated people. They wanted it to be hard to set up and use because it made them feel smart, it was absolutely ridiculous.
As soon as Plex got their UI to a design I liked I jumped ship and haven’t looked back.
