Manhattan Prep’s books are the gold standard in GMAT Prep, if you prefer studying from books. The current edition of All the Verbal is a compilation of three separate books in previous editions: Foundation of Verbal, CR and RC study guides. These books have been highly recommended by GMAT takers for I think more than a decade. You can search for reviews on the Manhattan (
MGMAT) books on GMAT Club.
The All the Quant volume is excellent as well. Especially, they have one chapter dedicated to each DI question type, a systematic lesson on DI which is rarely found. You can see the review here:

You can probably buy the Manhattan All the GMAT Set on Amazon ($109.99), the OG Bundle from Amazon too ($76.98), plus the Paid Official Practice Tests 3-6 from mba.com ($107.99), and come out with a slightly lower total price than buying the whole kit from Manhattan.
