The difference is that with Chorewars, other people are holding you accountable for whether you completed a task or not. I think this is an excellent idea, but, as many are thinking, what's to stop me from cheating? Tasks assigned to oneself privately are sometimes very abstract. If I assign myself a task, "be a good person today," I'm very likely to rationalize into thinking that I completed the task, whether I did or not.
