If it was just for me inside my house then I never would have left XBMC now called Kodi and a file share. I still run it with a special set top box to play 4K disc rips with full Dolby Vision / Atmos support.
Plex is dirt simple to get a reasonably secure setup for remote streaming with virtually no effort. User management and password resets are mostly managed by Plex and not me. I just have to setup what libraries I want to share with them.
I have a lifetime pass that I got for like $70-80. As long as it’s not broken, I see no reason to switch. Sure they keep adding garbage that I have to turn off but for the most part I can turn it off.
