ROG Xbox Ally vs. Steam Deck vs. Switch 2 comparison: Which handheld is best?

The ROG Xbox Ally is here, and while it’s not exactly a true Xbox — it’s made by Asus, not Microsoft — its marks a big moment: the entry of one of the game industry’s biggest players into the handheld market. This is a space which, not long ago, had been totally ceded to Nintendo. But now there is competition in the form of the upstart, if still relatively niche, PC handheld market. This market is led, and was created, by another massive player: Valve, with its Steam Deck. Meanwhile, Nintendo looks to consolidate its position and ensure its hegemony with the recently released Switch 2.
