Amazon’s Fire TV Stick gives you more of a traditional living room experience, where you can browse around different channels. While the Chromecast gives us a different approach and flexibility in terms of what you can do with it.  I hope above comparison helps you finalize whats best for you, depending on whats your requirement & what you want to achieve.

If you are considering upgrading your old TV to a smart TV i think Amazon Fire TV Stick will be the winner here which does more than just casting your phone to the TV.
