SCM gives you a schedule and TQ does not. TQ gives you a topic, gives you a list of books to go along with that topic and then it’s up to you to choose what you want to read and how much you want to cover in that particular topic. The author includes commentary on many of the topics, but not all. If you like a more relaxed approach and like to do your own planning, TQ is great. At times, I really like someone else to be giving me a schedule and at times I’ve preferred to go at our own pace. TQ might be a good fit for you if you already own many books, have access to a library with many good books, and enjoy planning and rabbit trails.
