For a Windows-first handheld, choose the ASUS ROG Xbox Ally X (2025); for a non-Valve handheld with SteamOS, choose the Lenovo Legion Go S SteamOS; for the strongest performance in this shortlist, consider the MSI Claw 8 EX AI+. There is no single best Steam Deck alternative: the right pick depends on whether you value Windows compatibility, a SteamOS-style interface, or premium performance most.

ASUS ROG Xbox Ally X (2025): best for Windows breadth
The 2025 ROG Xbox Ally X is the clearest choice if you want a handheld that runs Windows 11 and can access games that run on Windows. Xbox Wire describes an aggregated library for Xbox, Game Pass where available, Battle.net, and other PC storefronts, with an Xbox button opening a Windows Game Bar overlay. Game compatibility and service availability still vary by title, region, and account. See ASUS’s ROG Xbox Ally X (2025) product page and Xbox Wire’s launch announcement.

ASUS lists a 7-inch 1080p 120Hz touchscreen and a 60Wh battery for the 2025 ROG Xbox Ally. The platform’s Windows base gives it broad access to Windows games and storefronts, but that breadth does not guarantee every game will work well on a handheld screen or with controller input.
#1 Best Overall
- ALL GAMES, ALL PLACES, ALL YOURS – Get ready to game on the 8" 120Hz Lenovo PureSight display and launch any title using Legion Space. The AMD Ryzen Z2 Go processor and AMD Radeon graphics deliver incredible gaming performance.
- SEE EVERY DETAIL – Make every scene pop with 500 nits of stunning brightness and 100% sRGB color accuracy. And with 10-point touch support, your interactions are as precise as your aim.
- PLAY YOUR WAY – Play hundreds of high-quality PC games with your complimentary 3 months of PC Game Pass and EA Play. With new games added all the time, there’s always something new to play.
- POWER-UP AND GO – When it comes to gaming on the go, battery life is everything. The Lenovo Legion Go S is built with a robust 55.5Whr battery that delivers the long-lasting power you need for extended play sessions.
- TAKE FULL CONTROL – Get ready to dominate with the ergonomic Legion TrueStrike Controllers, designed for all-day comfort and precision. With their anti-slip texture, you’ll stay in control during even the most intense battles.
What to check before buying
- Confirm that the listing says ROG Xbox Ally X (2025). The ROG Xbox Ally X20 (2026) is a separate anniversary model, not another name for this device.
- Consider whether you are comfortable using Windows on a small touchscreen. Its launcher aggregation helps organize libraries, but does not remove differences between storefronts or game support.
- If you plan to connect an external monitor or peripherals, ASUS recommends the ROG Bulwark Dock (2025) DG300 or another 130W-capable dock. A dock is not required for handheld play.
Lenovo Legion Go S with SteamOS: best for a larger SteamOS handheld
The Legion Go S is the most direct pick for someone who wants SteamOS on a handheld from a manufacturer other than Valve. The cited SteamOS configuration has an 8-inch 1920×1200 IPS touchscreen with a 120Hz refresh rate and variable refresh rate (VRR), plus a Ryzen Z1 Extreme processor, dual USB4 ports, and microSD expansion. TechRepublic’s configuration and pricing details are at its Steam Deck alternatives comparison.
Trade-offs and configuration checks
The cited model has a 55.5Wh battery. SteamOS provides a more console-like handheld experience than Windows, but compatibility is not universal: some games rely on unsupported anti-cheat systems or Windows-specific software. Before buying, verify that the listing is the SteamOS version and check its memory and storage configuration; the Legion Go S is also sold in other configurations.

MSI Claw 8 EX AI+: best for premium performance
In the cited comparison, the MSI Claw 8 EX AI+ is the performance-oriented option. TechRepublic reports that the CG3EM-024US configuration has Intel Arc G3 Extreme/Arc B390 graphics, 32GB LPDDR5X memory, a 1TB SSD, and an 80Wh battery. Its 8-inch 1920×1200 IPS touchscreen supports VRR up to 120Hz. TechRepublic cites Tom’s Hardware benchmarks for performance; those are attributed results, not a test of this guide.

How the tested gaming runtimes compare
Tom’s Guide’s 2026 roundup reports the following gaming runtimes from its own tests. These are publication test results, not guaranteed battery life; actual runtime changes with the game, settings, and adjustments.
| Model | Tom’s Guide tested gaming runtime | Battery capacity in cited configuration |
|---|---|---|
| MSI Claw 8 EX AI+ | 4 hours 10 minutes | 80Wh |
| ASUS ROG Xbox Ally X (2025) | 2 hours 56 minutes | Not stated for this exact Ally X configuration in the cited product details |
| Lenovo Legion Go S SteamOS | 1 hour 45 minutes | 55.5Wh |
The runtime figures come from Tom’s Guide’s 2026 Steam Deck alternatives roundup. Battery capacity and tested runtime are different measures: a larger Wh rating does not by itself predict how long a particular game will run.

Keep the 2025 Ally X separate from the 2026 X20
ASUS’s US product page lists the ROG Xbox Ally X20 (2026) at $1,299.99 and describes it as a separate anniversary model with an OLED screen. It is not the 2025 ROG Xbox Ally X compared above. Prices and availability can change; consult ASUS’s US ROG Ally product listings for the distinct model listing.
