What really sucks on Apple TV is the YouTube app. It may be Google's single least competent publicly available software engineering.
edited to clarify question
I can use it with the same remote as I turn my TV on with.
In all honesty, these things all are just feature parity, they perform the exact same between the two devices, but I really feel like the UX of fast-forwarding, rewinding etc is completely MIA on Apple TV and therefore it isn't really superior to the native applications, despite the $200 price point
Any modern TV will let the connected turn it on and off with HDMI-CEC. For Apple TV, you just use the volume or whatever button to turn it on, then hold the home button and tap sleep to turn it off. Roku supports this, too.
