I hate modern Simpsons, but enjoy classic (lets say stopping at S12) Simpsons.
Meanwhile I loved old S1-4 Futurama (hell, I'd argue its probably among the best in terms of consistency in episode quality), and movies I found pretty alright, but I kinda fell out of keeping up with the Comedy Central episodes. Though what I did see was for the most part alright. Not as consistently fantastic as the Fox episodes, but also not near as abysmal as modern Simpsons has become.
I don't even have Cable though, so I'm not sure when (if ever) I'll get to watching. But if I do, then I think the bulk of my enjoyment will be based on which side's creative voice is more heard for its production.
