Hello guys. I know it's a relatively long comparison but I really need to understand their differences before diving into any of them. I am currently at 640 (Q48 V29). I need to touch 700 and I have almost 6 weeks. What's my best bet? Which one of these books is better for improvement (mainly in verbal but in quant too)?
GMAT books are my wheelhouse

The answer is fairly simple. All of these books are designed to work together. The good part is that there’s no overlap… eons ago I prepared using the Kaplan books as well and I used the main book in conjunction with the workbooks. I personally like the workbooks the most they seem to have a lot more practical and very straightforward advice that I need it for my specific target areas. I think the workbooks is what helped me improve my score of the most the main books seem to be too general and didn’t go deep enough in my experience.
I studied pretty much from scratch or from 540 after wasting a lot of time with the Princeton review book which did not get me very far. I have not used GMAT 800 for my prep, but it’s worth poking around and use it as a staying fresh, while you are honing some of the weaknesses. What I mean is that if you were focusing on verbal, you don’t want to completely ignore quant. You need to do some practice and review and so you could potentially study quant for 30 minutes from that book per day. If I remember correctly, it doesn’t actually have a lot of materials or rules or studying and it’s mostly question collection.
The strategies and approaches that Kaplan has generally match what Manhattan has. However, Manhattan goes a lot deeper and is a lot more thorough but it will probably take you double the time to cover it.
Looking at your current score, it seems like you can mostly help in verbal so I can see getting the verbal in the quanta workbooks and start in the verbal workbook and use the quantum workbook as a refresher so to speak. It has some fantastic questions in it. It took me a number of passes to realize how elegantly some of them could be solved. The book authors did not seem to realize that themselves, or at least they included more traditional explanations, but some of the arithmetic questions can be solved faster and more elegantly. I did not realize it until after I already was done with the GMAT and I was helping someone else study. 😂
You should be able to cover the variable workbook in about a month or six weeks.
