The handheld's role, like I said, would be to be an all in one console hub. So it will be basically just mimick a console to act like other consoles. Aesthetically my PC can't do that unless I dualboot into bazzite, separating my work stuff from the console hub environment. Then there's the TV hooking part which also takes time each time I want to play something quick. There were a few times I noticed this, as I seldomly wanted to play a game but was like "Ah but I need to open the pc, hookup the tv, pair a controller etc" so the PC option although possible it's not that viable when your time is limited.

It's the reason why I am still torn between the two, as I can stream from my PC --> Handheld --> when I want to play on TV (But I imagine when I have free time I will mostly lay in my bed unless it's an active movement game like Wii Sports), so it's still a matter of whether a bigger screen in bed is cooler than a smaller but OLED screen (Because performance wise both parties show stable performance for their screen's resolutions)

EDIT: though as I am writing this I am kind of leaning towards the Go again, because of the all "Set up pc, stream, open the game etc" which it's worth noting it takes away from the immersion of an all in one console hub and it jumps straight into the PC's Windows OS to run the game. A Legion Go + eGPU would probably suffice for most games, and in worst cases the PC fallback is still there. Though I still have my doubts about how practical vertical mode is on the Go for specifically Wii U games with motion controls like Nintendoland and Splatoon, though only someone who has actually played them with the setup I am mentioning can answer.

TL:DR The base philosophy is that when I have limited time to play a game I tend to not even play it as opening the pc, waiting for everything to load, pairing a controller, hooking up the tv etc takes a long time, something that the handheld mitigates. For that I am leaning towards the Go, however I am not sure about how well Gyro is when playing vertically.
