Both the ROG Xbox Ally ($599) and the Steam Deck OLED ($549–$649) are high-end horizontal handhelds capable of emulating up to Wii U, so the choice comes down to ecosystem and software. The ROG Xbox Ally runs Windows 11 with tight Xbox and Microsoft Store integration, suiting buyers already in that ecosystem. The Steam Deck OLED ships with SteamOS 3.0 but also supports Windows 11, offering more OS flexibility and a mature handheld-optimized interface out of the box.
