Yes, the Nvidia GPU in the Switch 2 is more powerful. But not the ARM CPU.
The existence of Nvidia DLSS (upscaling and frame generation) alone is a huge advantage over the Steam Deck, too. The Deck can't use DLSS because it's Nvidia only, AMD FSR isn't as good, and the latest FSR isn't even supported (officially) on the SoC.
