Chromecast is a the name of a service like Amazon's Firestick. It allows you to turn your TV into internet ready by broadcasting from your computer (Google Chome, hence the name) and turning your regular TV into an internet TV. Whatever other feature are activated by Chromecast it is still more or less just a regular TV without your computer. This is a ROKU which is a stand alone internet ready smart TV. With it I can stream Netflix, Hulu, and Amazon prime directly from the TV (wireless capable or LAN) without having to use my computer. That is the drawback of Chromecast. You have to have you computer connected to the TV. That means that you cannot use your computer for other tasks while streaming. With a ROKU TV like this you can still "cast" your computer to your TV so if you are playing a video game and want a larger monitor you are set.
