Any suggestion on those grouped by categories books?

there are three companies selling on amazon, powerscore, cambridge, Traciela
cambridge and traciela both claim they arranged not only by question type but also by difficulty
i'm not sure whether powerscore's also group by difficulty (seems not), but it's the cheapest
any suggestion on which one to get? does the difficulty grouping thing matter?
