Should I buy the ASUS ROG Ally Z1 Extreme?

Yes—buy the ASUS ROG Ally Z1 Extreme if you want a powerful Windows handheld for PC games, especially if it is meaningfully discounted. It’s the better Ally to buy over the regular Z1 because the Z1 Extreme version can deliver much stronger performance in demanding games.

Skip it if you mainly want the simplest console-like handheld experience or long unplugged play sessions. Windows gives you broad launcher and game compatibility, but it also makes the experience less frictionless than a Steam Deck-style interface.
