Handheld Gaming in 2025: Steam Deck OLED vs. ASUS ROG Ally X vs. Lenovo Legion Go — Which Should You Buy?

Handheld gaming has had an absolute renaissance. What started with Valve’s Steam Deck cracking open the PC handheld market has exploded into a full-blown category war, with ASUS, Lenovo, MSI, and others all competing for your pocket gaming dollars. In 2025, the options are better than ever — and choosing between them is genuinely difficult. We break it all down.

The Contenders

💚 Valve Steam Deck OLED

Valve’s updated Steam Deck with an OLED display is still the benchmark by which all handheld PCs are measured. The OLED upgrade was massive — the screen is significantly brighter, more vibrant, and has much better battery life than the original LCD model. The Steam ecosystem is unmatched, SteamOS is the best handheld operating system available, and the price point remains the most competitive in the category.

Pros: Best software experience, SteamOS, best value, massive game library, great community support
Cons: Less raw power than Windows competitors, less RAM (16GB vs 24GB on some rivals), no detachable controllers

🟥 ASUS ROG Ally X

The ROG Ally X is ASUS’s refined, more powerful follow-up to the original ROG Ally. It packs AMD’s latest Ryzen Z1 Extreme processor, 24GB of LPDDR5X RAM, a 1080p 120Hz display, and a significantly improved battery compared to the first generation. Running Windows 11, it has access to every PC game storefront — Steam, Epic, Xbox Game Pass, and more.

Pros: Most powerful handheld, Windows ecosystem, XG Mobile external GPU support, 1080p 120Hz display
Cons: Windows on a handheld is still clunky, more expensive, runs hotter

🟦 Lenovo Legion Go

The Lenovo Legion Go took a bold approach: detachable controllers (similar to Nintendo Switch), an enormous 8.8-inch QHD+ display, and a unique “FPS Mode” where the right controller detaches and acts as a mouse. It’s the most innovative design in the handheld PC space, and the large screen makes it a genuinely different experience from the competition.

Pros: Largest, sharpest display, detachable controllers, innovative FPS mode, great for media consumption
Cons: Heaviest and largest of the three, Windows software experience, premium price
