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?
Even though I'm big on FOSS, that seems like a completely reasonable take. Though I think Jellyfin integrates with Kodi much better. Last time I used Kodi + Plex, Plex was its own app inside Kodi. Meanwhile, with Jellyfin it just populates your regular Kodi with the media without you even noticing that the source is Jellyfin and not say your hdd.
