I am facing this same dilemma. They all seem to cover *something* that DS doesn't yet know (either math or non-math), but it's hard to know what the cutoff should be. DS's math skills are all over the map, so anything other than individual tutoring is going to be hard to fit.
I am trying to borrow a selection of the elementary and intermediate books from friends before we buy any.
eta: FWIW, DS finds EPGY pretty dry, and I don't see it as a long term math curriculum.
