As a Kaplan Teacher (in training) I can say that their classroom material is very good quality stuff. The CATs are difficult, but like everyone here says, the harder questions (like GMATClub Challenges) make you better. Kaplan is an advocate for plugging in numbers, but not in every case. As you said, there are some questions that it just doesn't work. There are others, that for the vast majority of testers, plugging numbers is going to be the fastest way to tackle a tough problem. There are people that can do any problem without plugging numbers, but plugging numbers in where it can be helpful, does work for everyone.

Not to sound cocky or anything, but Kaplan should change the name of the book to Kaplan 700 or the likes since the question is definitely not that hard. I found that the GMATClub test questions a lot harder. And the explanation for the answer is abysmal at best particularly because they are a big supporter of "plugging in numbers". I'm not against this strategy, but some questions really can't be easily solved by plugging numbers because on a 800 questions you will likely find 2-3 answers that fits your pickup number if you don't pick broad enough. In fact, all 800 (or at least 99 percentile) test takers I know (which is not much by the way) rarely use plugging number method.
I'd say, if you have a strong basic, you better go with Kaplan's CAT test as it offers a better tough question that is challenging compared to their book. I've heard first hand from former Kaplan student that their classroom material is far faaaaar better than their books (obviously, their tutor is their money making machine, not their books)
