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)
I would imagine the guerillas were pretty good at maintaining hygiene, since that was the number 1 killer in most wars until quite recently. So Uncle Ho, Stalin, Fidel, Che, Tito, Kim and so on would be fine on that front
