Google Chromecast 4th Gen with Google TV 2020 4K Streaming Media Player?

My TV is an old 4K Smart TV Model and I don't have the means to buy a new TV. Ang meron lang sa TV ko is Youtube and Netflix. Plano ko sana bumili ng Google Chromecast 4th Gen with Google TV 2020 4K Streaming Media Player. Alam ko discontinued na 'to ng Google pero ask ko lang sa mga may gamit neto, worth it pa ba to own it? I mean, anu anong streaming apps ang gamit nyo to watch your movies from using this? Salamat sa sasagot po.
