If the deck can run the game at a detail level you like, you should play it locally. Otherwise, stream it. I love game streaming, I used an iPad and an Xbox controller to play 200 hours of skyrim while I lived in a place that was too small to setup a desk, but it’s never going to be as good of an experience as local play. Even with my PC wired directly and the iPad having agreat wifi connection it would still occasionally have a poor connection or the quality would drop.

Apple did the same thing with the M2 Chip, compared their performance to “the latest Intel Macs” 3 years after releasing the last Intel Mac. It’s all a stupid game
