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?
It's easy to install a different launcher. I've literally never seen an ad on my Shield…And the ads are the fault of Google TV, not the Shield.
My issues with the Shield are mostly the cost and then killing software features.
