I bought Chromecast w/ Google TV and got Shield Pro as a gift - am planning to return one. I am a long term Apple TV user. In fact, the main TV in my living room is hooked up to an Apple TV 4K which I have no complaints about.
The Chromecast w/ Google TV is something I bought to turn my bedroom computer monitor into an occasional TV for the times when the Living Room TV is otherwise occupied.
So the question is, which one should I return? The Shield Pro is definitely the one that provides the better experience. The UI is snappier, although I prefer the Google TV interface (unpopular opinion, I know). And the AI upscaling is usually an improvement on older content.
I have an Xbox for gaming, so have not used Shield for that purpose so far.
So what does reddit think? Any chance the Shield TV is getting the Google TV UI? What else would I be missing if I chose the Chromecast?
Another factor to consider is that if I am going to use a $200 device, I might as well get another Apple TV which integrates better with my mostly Apple household.
To be clear, I have not had the chance to explore them thoroughly - been busy with other things. And I didn't want to decide based on initial impressions.
The chromecast can play YouTube hdr, not the shield.
For everything else the shield is more feature rich and the extra storage will help in the long run.
They also now allow 4k hdr and atmos from the apple tv app, since this morning with the android 11 update, which is nice
