I used Kodi for years (back before and during the XMBC - > Kodi shift) before moving to Plex, it was great (a pain for a good config, but once your clients have remote access and use a shared database its insane how good it can be) but Plex was touted for so long I figured I’d give it a try when I saw a good sale. I’ve been using it for the past 8 years or so but may go back to Kodi or Jellyfin.
