A lot of times I game when friends are over and we chill on a couch and pass around a controller, so Xbox. I also game on a PC but really for games that are only pc (Age of Empires) or games that I want to try modding out (GTA).
I actually have GTA and Witcher 3 on both PC and Xbox. I play GTA online on the xbox, and tons of modding fun on PC. Similar with Witcher - I play story on Xbox when people are over but just mess around with mods on PC.
