Dude I’m a D1 Steam Deck glazer but the two systems couldn’t be more different and they compliment each other perfectly, First of all, Switch 2 is vastly vastly more powerful. Like not even close. You cannot get a better system for this price right now, especially not a hybrid that will get endless exclusives.
Steam Deck is for getting like 10 games for $100 on sale and emulation so you don’t ever need to buy overpriced rereleases. I got Doom 2016 for $5 on there and it’s a perfect experience. That game is $25 on the OG Switch and is vastly compromised for that things power level.
Switch 2 is for playing Nintendo games, whatever other exclusives will release like Duskbloods and games like Cyberpunk, Elden Ring and Hogwarts Legacy (hopefully Indiana Jones down the line) that barely function on Steam or other handheld PCs.
I don’t know why the internet has decided to pit these two systems against each other when A: the power difference is so vast that they aren’t really worth comparing and B: they actually compliment each other perfectly and the Steam Deck is an undeniably niche product that isn’t going after the same market at all
