I often wondered what he meant by the set not being quite as good; I have it now myself, and would like to clarify. The verb cards have only the first principal part, lacking the other five; all the cards lack the lists of similar Greek words (i.e. in the Classical set the card for the verb "to live" will also have the words for "life, course of life"; "life; living, sustenance"; "worth living"); and there are no English cognates and derivatives. The lack of principal parts is a serious problem; the other two are pleasantries which can be done without.
For what it's worth the noun cards do offer the genitive singular endings in addition to the nominative singular.
A good set if you like to have your Greek words printed, instead of sloppily scribbled; but if you're expecting a lot of nice extras you may be disappointed.
