I don't do much handheld gaming, but I'm going to have some overseas flights and long-ish train rides later this year, and may also be having surgery that will keep me fairly bedbound for about a month. I'm just not sure how much money it's worth spending on a deck that I likely won't use much outside of those specific cases - I bought a switch when I got covid in 2020 and used it a ton at the time but I've only used it a few times since, though I miiight use a deck a bit more just because I already have a pretty extensive steam library.
Is it better to stick to the cheapest model or is there enough of a difference that it might be worth spending a little more for a nicer one?
I recommend getting the OLED 512GB because it can store plenty of games and it's better in every way over the LCD model.
If your budget is absolutely limited, then the LCD model is also great.
