Well it should be obvious that actual Android TV would be better than a crappy rebadged normal android experience pretending to be android TV, but even from a hardware experience, the Chromecast seems better, runs smoother, its a better experience overall.
I've seen the older Chromecast and just didn't like the only casting option. Now that it has AndroidTV built in this is a great little piece of kit.
And yes I could still sideload that handful of dodgy apps I use, but even beyond that I would have to recommend ditching the dodgy boxes and going true Android TV.
Same price more or less, better experience overall.
wtf is a chromecast snow?
