It all depends on how folks define "better". Perhaps an Android box allows you to find more content. I don't know. I can vouch for the plug and play of the Firestick 4K and also the top notch audio and video processing.

I don't use Kodi. Apparently Kodi can be installed on the Firestick.

Netflix, Amazon Prime, YouTube and Spotify are top notch.
