Like Roku TVs, a Fire TV comes with lots of streaming apps: Netflix, Hulu, HBO and so on. (No YouTube, though, which is a definite deal breaker for some.) And you get the benefit of an Alexa-enabled remote, so you can just tell the TV which channel or show you want.
What's more, Fire TV affords access to various Alexa skills and a huge library of Amazon apps. For example, you could play the excellent party game Quiplash -- something Roku can't do.
