Based on my knowledge of the cutoff date (September 2021), the latest Amazon Fire TV Stick is the Fire TV Stick (2021). HDR10+ and HLG high dynamic range formats are supported, and this version features a faster processor than previous generations. As part of its functionality, you can also control playback with your voice, launch apps, and search for content using Alexa.
It really depends on your specific needs and preferences when it comes to the “best” Firestick version. The third generation Fire TV Stick is the best choice if you want the latest and greatest features. On the other hand, if you’re on a budget, an older version like the Fire TV Stick (2nd generation) may still be a good option for you. Choosing the right Firestick version for your needs and budget comes down to comparing the features and specifications of different versions.
