Ok...I'll try it like this...It's tough to make a blanket statement like this as it is really dependent on the audience. Myself, as a father of two young children, really enjoyed Story Book Circus as it was geared for my children's age which made it enjoyable for our family. I suspect however that most older people (adolescents and up) would clearly favour the the new Simpson's area as they are more likely to know the simpsons than my six and three year olds do. To me it's not really comparing apples to apples as you need to look at the parks as a whole. Regardless (or irregardless) I think looking at it from this meta perspective makes the debate more meaningful.
Simpsons > Storybook Circus for everyone over the age of six.
(True, it's a generalization. For all I know, some kids under six may also prefer Simpsons. I don't associate with people whose age is in single digits, so I'm basing my theory on pure assumption, guesswork and geniusness.)
