I have a google chromecast (w GoogleTV) and the UI and lag is becoming a nuisance.
With Apple TV, do you get apps like Twitch and YouTube? Do livestreams work well? The most common apps I use are Twitch and YouTube but also Max, Netflix, Crunchyroll and Amazon Video.
I also had a Chromecast 4K and the Amazon Cube. For me, both are not at all comparable in terms of quality. One of the best features on the Apple TV is the remote control. Thanks to the touch surface, it is ideal for gaming.
Counter opinion: The AppleTV touch remote is a device which I absolutely dread picking up when I can even find it. Nothing in my house gets screamed at except for the AppleTV touch remote. I hate it. HATE IT!
I like the built quality but it does get a little slippery. I wish there was a play next/play back and not just the scrub back/forward.
I found nice silicone covers on Amazon for all my remotes. They can now hang vertically on the back of a couch without slipping down.
