The short answer
The ROG Xbox Ally X (score 81, $999.99) is the best handheld of the three and the fastest PC Gamer has tested, but the ROG Xbox Ally (70, $599.99) is the better buy for most people, because it costs $400 less and keeps the same Xbox-style software. The Lenovo Legion Go S with SteamOS (73, $949.99) is the pick only if you want a Steam-first handheld and can accept its short battery.

What each handheld costs you
- Ally X: PC Gamer called it expensive and noted a dull screen; it is still a Windows PC, not a console.
- Ally: the weaker Z2 A chip and 16GB of memory limit it in demanding games.
- Legion Go S: Tom’s Hardware praised its performance but noted a price to match, and its 55.5 Wh battery is the smallest here.
