I’m thinking Engels. Responsible, reliable, motivated, has money, knows how to manage it and is incredibly generous (he died with more than he gained from the factory sale despite supporting the whole German/communist underground in London).
Also who’d be worst? Would Marx ever catch up with his chores? Would Che disappear suddenly for months at a time?
(Not a very serious question obviously)


Engels was a notorious womanizer and there’s a plausible claim that he impregnated Marx’s housekeeper. That should subtract roommate points.
I would want Ho Chi Minh. He worked at a bunch of fancy bakeries in Paris and NYC and knew how to cook well.
god forbid a dude have a hobby!
Those are really good points, especially the baking.
