Vita owner here. Nobody in my family ever owned an original Xbox. But I played at some acquaintances house's sometimes. Plus some third-party titles for Xbox I've played on GameCube, PS2, or PC.
With all that in mind, I'd probably say an original Xbox. I played the KOTOR duology on PC and they're amazing. You also have the original Lego Star Wars games and the original Star Wars Battlefront games. Not to mention other games.
