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?
I know they could close up shop tomorrow, but the one-time-purchase of plexpass beats any sort of ongoing subscription. It does a great job of finding subtitles, it doesn't care how shit my file/folder structure is, and the client is user friendly for the rest of the house.
I prefer jellyfin, but I haven't taken the time to get my library in the right layout for jellyfin to display it right.
