My Apple TV has a pretty good range. I have to have an extender for my computer and phone to get a reliable signal in my bedroom, but the Apple TV picks up the main signal fine.
I have a Fire Stick that I take to hotels because it can handle captive portals, and I don't ever have a problem on usually unreliable hotel networks. I don't have a comparison to the full Fire, though, but I like the portability of it. I keep it in my suitcase in a small pocket and don't have to worry about it.
