Quick answer: The 4K Plus is enough for straightforward Fire TV streaming. The 4K Max is the better long-term buy if you install more apps because it offers 16GB storage instead of 8GB and moves from Wi-Fi 6 to Wi-Fi 6E.
What they share
Both are compact Fire TV sticks with 2GB RAM, 4K support, Dolby Vision, HDR10+, Dolby Atmos and Alexa voice control.
The important difference: storage
Amazon specifies 8GB for the 4K Plus and 16GB for the 4K Max. That difference matters more over time than small benchmark gaps because system files, app caches and updates all consume internal space.
Networking
The 4K Plus supports Wi-Fi 6 while the 4K Max supports Wi-Fi 6E.
ViewHarbour verdict
Buy the 4K Plus if the price gap is meaningful and your app list is small. Buy the 4K Max for a primary television or heavier app use.
