My 512GB Steam Deck, easily. I've used it almost every day for going on a year now, and the novelty of playing things like Witcher 3, or Mass Effect, or a fully modded Skyrim anywhere I want still hasn't worn off.
A Steam Deck is of of my best purchases, I don't feel trapped in front of a console or PC. I can game outside, in the living room, on vacation, and on the toilet. I've completed more games this year already than I have in years!
