I'd pick Cedar Point over Disney, though I've never been to either one. Main reasons would be due to me being a coaster addict, also Cedar Point is a long ways cheaper than Disney. Another reason would be that I've never really had a Disney appeal, even as a child. I don't know why, but for some reason I just never liked Disney Channel or had a passion for any of their characters. In fact, the only show I've ever that had a Disney character was the episode of South Park that had the Jonas Brothers and Mickey Mouse as their manager
But back to the theme park world, Six Flags Magic Mountain was probably the most memorable experience I've had at a theme park, which I had in 2012 when I was 13 (I'm 15 now), and if Cedar Point is considered to be better than that, then I'd pick that over ANYTHING.
