How well do these apps work with livestreams? That's been YT's secret sauce for me personally. While their player isn't perfect, the way that YT handles livestreams is far and away its most valuable feature. No other platform will allow you to pause a stream, walk away for 2 hours, and come back and let you press play where you left off. On mobile and desktop, it works great. I've had more issues with the YT player on Apple TV but I don't tend to pause streams with that device.
