What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
Valve Steam Deck OLED
Three whitelisted testers with hands-on lab measurements — Tom's Hardware, Tom's Guide and Engadget — agree the Steam Deck OLED is the definitive Steam Deck: the brighter OLED/HDR screen (measured ~597 nits SDR, ~969 nits HDR) and longer battery are genuine wins, but gaming performance is essentially unchanged from the LCD and the chassis stays bulky. (3 sourced reviews, 3 lab-tested.)
Praised: Bright, vibrant OLED/HDR display (measured ~597 nits SDR, ~969 nits HDR); Lighter, more comfortable-to-hold chassis (about 30g lighter); Cooler, better-managed thermals without extra fan noise.
Flagged: Gaming performance essentially unchanged from the LCD model; Large, bulky form factor unchanged from the original; Battery still drains fast in demanding HDR titles.
Asus ROG Ally X
All three whitelisted testers (Tom's Hardware, Engadget, TechPowerUp) rate the 2024 ROG Ally X the best Windows handheld at launch, praising its doubled 80Wh battery, 24GB RAM performance gains and comfier grips. All flag the $799 price and clunky Windows. A newer rival (MSI Claw 8) later out-lasted its battery. Excludes the separate 2025 Xbox Ally X. (3 sourced reviews, 3 lab-tested.)
Praised: Doubled 80Wh battery delivers much longer runtime than the original Ally; 24GB of faster RAM lifts gaming performance on the same Z1 Extreme chip; Improved ergonomics, larger grips and better build comfort.
Flagged: $799/$800 price is steep, especially versus the cheaper Steam Deck; Windows 11 still feels clunky with a controller on a small handheld screen; Armoury Crate software remains buggy / less cohesive than SteamOS.
