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?
Jellyfin app is bad on android TV and being in bed with media conglomerates doesn't get in the way on plex imo. Open up my plex and there are no ads and the only two categories are TV and movies which I put there. I WILL switch to jelly, when their TV app gets more features.
