Help I’m confused now

So I’m been trying to figure out for a little bit what I want between a Asus rog ally vs a steam deck. Came to terms with the Rog Ally. But now I see this device and it looks spectacular. But is it worth the $700 price point? I’m getting a Asus rog for $460. All I wanna play is single player games,switch emulators, ncaa 14. If that gives you an idea
