Personally, I think it is harder to win a Derby than a Qualifying.
Especially, if you start out training with AA stakes in mind and view the Derby as just a stepping stone to Qualifying then on to AA stakes. A lot depends on the entry size of the Derby or Qualifying, as to their level of difficulty. But, a good dog that is well into advanced training should be able to win a Q well before 2.5 years of age.
