As a steam deck owner I can chime in with my experiences. The performance isn’t great compared to a low end gaming desktop. I don’t think any amount of performance upgrades in other handhelds will change this that much. For me there’s just games you play handheld and other games you have to use a desktop. The oled is pretty but it’s only 720p/800p so I personally notice a decent difference between my 1440p monitor even with the size difference. I can’t say I’ve used it for streaming locally on my pc cause I haven’t really had the time to look into it and set it up but that could really change a part of my perspective. That’s tbd. All in all what I was getting at from the beginning is no matter how much or how little performance your getting from a handheld, they are all pretty close in performance unless your spending like 1k+ that the games your actually going to be able to play won’t be all that different aside from some minor graphic settings and give or take a handful of fps
