I know the conversation usually ends up being about who contributed what, or who was more in the wrong about such and such, but I'm more curious to know which you'd judge to be better based on artistic merit alone. Based solely on the ideas, characters, and works we factually know each was responsible for, which was the better creator?
Anyone who's read enough of my rambling knows my opinion, but I'm curious to hear yours.
And please try to avoid "dissing" either creator, as that will inevitably ruffle someone's feathers. Let's try to keep the discussion focused on the positive.
