I went through quant part of NOVA GMAT Prep and didn't find it useful and felt that difficulty level is not for 700+ score. I was disappointed and didn't do verbal part from the book.
I'm going back to OG and GMATClub forum questions.
PS I had older NOVA GMAT Prep from 2005. I'm not sure whether material in newer books has completely changed.
