Buy a Sky Cipher Xbox Controller, Get a Fire TV Stick 4K Max and Game Pass for Just $10 More for Prime Day
If you're intending to get the Fire TV Stick specifically for Xbox Cloud Gaming, I'd recommend you spend the extra $10 to get the 4K Max. It has the most powerful processor, but more importantly, it supports the Wi-Fi 6E protocol. The speed and reliability of your internet connection will directly correlate with your cloud gaming experience.
