Sounds like you don't want to do this, but I am loving my Nvidia Shield TV Pro.
I've installed Projectivity Launcher on it and all the apps I want. It's such a smooth, clean experience.
Whether it's Netflix, Tivimate, Kodi or Plex, it all runs super smoothly, no stutters, no ads. Highly recommend.
The backlit, voice capable remote is really nice too.
It's long, but well worth the read.
