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 for sure.
Marx reminds me of a couple of roommates. Awesome conversationalists, really chill, but just no consideration for anyone else in the household and being awake regularly at 4am making the occasional noises that wake me up. Annoying, but not annoying enough to fantasize about putting an icepick through their brains.
Marx is a hot couch guy with unknown neuroatypicality
So by that I’m guessing Trotsky is your nightmare roomie
He’d leave Passive-agressuve notes everywhere
It would no longer be icepick fantasies, it would be icepick realities
