I know I will get a biased answers here, but I’m wondering which one to choose.

I’m completely new to handhelds so any advice is great. I mainly play factorio and some other rather non demanding games. I want to be able to play games from gog too and other non steam games. Anyway, rog has Windows so I’m wondering if that’s not better for how I plan to use the handheld.

I’m thinking about getting it for myself for Christmas so I still have plenty of time to decide. What would you guys suggest?
