Both FireTV and Android TV have voice control via their remotes. Both have universal SDKs between TV, Tablet and Phone. Neither have touch enabled remotes or motion sensitive remotes, but both have traditional console game controller accessories and full blown (PS3 quality) gaming hardware.

I assume that the AppleTV will also support the various iOS-compatible game controllers which exist.
