Google have really hamstrung the Android TV ones, but most of the media boxes you get off Amazon won't have that. I have the Xiaomi MiBox 3 and it's a pain to put other apps on it. Anything that isn't explicitly Android TV compatible won't be installable from the Play Store, and even if you sideload it, it doesn't show up in the menu. Amusingly, this is the most useful that "OK Google" has ever been (Xiaomi's remote+voice control is excellent) I will say it's worth reading up and buying based on chipset+firmware. You probably want Android 5+, something that runs Kodi well, Ethernet and HEVC decoding. I'd recommend the Mibox but Google and Xiaomi have really made a mess of it.
