I went through the MGMAT quant books, and am now going through quantum. I really like it so far. You can ask me any questions you have about the product. I originally bought quantum because I wanted to have video explanations for quant problems for GMAT prep question pack and all the questions for gmat prep test questions. But I found his course is really good too. It contains a lot of DS questions which is nice sine MGMAT don't seem to cover DS very much. It also covers many uncommon types that are not covered in MGMAT. He covers the material from the basic to the most difficult problems so it would be helpful regardless of what your ability level is for quant. Let me know if you have any specific questions. Good Luck!

I've not familiar with Quantum GMAT, but I've used the GMATPill. I think it's very good if you're self-motivated. Zeke (the founder) has made extensive revisions and updates to the GMATPill over the past couple years and it now has over 60 hours of video. He also has a free "Practice Pill" platform which has hundreds of practice questions. The best thing about the practice platform is that you can see the % of people that got a question correct, and use that as a rough gauge of the difficulty level.

I wrote a longer review of the GMATPill here.
