Sorry but you are wrong.

ETS guide is useless, they are two careful to teach and guide.

Further, Big book is obsolete as GRE is done with analogies and antonyms.

Best books.

Manhattan series
Kaplan 2014 premier
Barron's

And finally Princeton's wordsmart for GRE.

That's it. Maybe hoodwink took GRE 5 years ago, but as far as "modern" world is concerned you are wrong.
