I’ve got a Switch and a Deck, and I can’t fathom all these replies saying the Deck is just as good for Switch. It’s not, and it’s not worth playing games at 90 or 95% performance when you want 100% performance. “Playable” to “native performance” is such a big step. Plus, it costs more.
I’d honestly suggest using your ears and deciding if you can tell the difference. My music library is under 20GB so I do not fuss too much, but I am not truly sure I can tell the difference.
