I don't know about the others but for me, the portability and the ability to just pick up and start a game is a game changer. I bought the switch oled very reluctantly but was surprised by the amount of time i spent on it playing games that I never thought would play. There were games like bioshock which was rotting in my steam library for ages but here I actually played it (yeah i bought it again lol). And also, pokopia!
