Ginger's smarter and it's not close.

Given time, Ginger should be able to understand almost anything. She won't have the breadth of understanding that Fred does, but she will have the same depth of understanding. Only she goes one step further - she'll come up with new understanding. Because she's also conversant on the old understanding, she will be able to use her insights effectively (which the other version Ginger could not do because of her handicap).

Ginger will also perform tasks solidly after learning the relevant concepts and when to apply them, but her occasional flashes of insight will lead to significantly better performance at most tasks. This benefit should eventually make up for the cost of spending more time learning.

Obviously Fred will do well for himself, and he may appear smarter while he's young, but eventually Ginger will overtake him as her insights become more relevant. Ginger will be the one who makes history.
