For those who want to read Bavinck's Reformed Dogmatics but may find that his 4 volumes are too much for them, do consider picking this abridged version instead. And even for those who are ambitious enough to read his 4 volumes, I would still recommend them to read this abridged version first before the 4 volumes. That's because it's very easy to be lost in the details from the 4 volumes and lost sight of the big picture, hence I recommend reading this abridged version first.
This abridged version is also better than Bavinck's Our Reasonable Faith/Wonderful works of God because it's more technical and deeper. Almost all the words in this abridged version are taken directly word for word from the 4 volumes themselves.
From this abridged edition, most of the historical theology details are removed except for the more prominent ones like Augustine, Thomas Aquinas, Martin Luther, Zwingli, Calvin, and so on. And most of the core biblical and theological arguments were kept in this abridged edition. So in essence, readers wouldn't lose out much on Bavinck. In fact, I would argue that this abridged edition would be sufficient for most people. In my opinion, reading the 4 volumes are not necessary, one can probably choose to move on to Francis Turretin's Institutes of Elenctic Theology after this abridged edition which is way more deeper and technical than the 4 volumes of Bavinck which I think might be better. But there is no harm in reading all 4 volumes after this abridged edition if one would like to learn more about historical theology and some additional theological arguments which are omitted from this abridged edition.
You don't need the 4 volumes to see how brilliant Bavinck is. Just this abridged edition is more than enough. Theologians like him who write brilliant systematic theology do not appear in every generation or century. They only come once in a few centuries, like Augustine, Aquinas, and Calvin. In this volume, one can see that not only Bavinck is well versed in biblical languages, biblical studies, and systematic theology, but he is also very good at interacting theology with science, history, philosophy, psychology, legal system, humanities, ancient near east culture, critical biblical studies, different denominations, and different religions.
Personally, while I still think Berkhof's one-volume systematic theology is the best, this volume is nevertheless a very close second and it will complement Berkhof's nicely.
Those who are familiar with modern systematics (like Grudem/Frame) or biblical studies work might find Bavinck's exegesis on some difficult topics to be quite lacking. To my knowledge, this is because he used a different approach. For some of these topics, instead of trying to exegete an unclear passage, he will interpret the unclear with a clearer passage, or if not, use good and necessary consequences (aka logical deduction/infer) deduced from scripture to justify his theological position. Just for comparison, his contemporary, Geerhadus Vos will take a more exegetical approach, especially on highly debatable and unclear passages to justify his theological position. In my opinion, I think Bavinck's approach is much better because I find myself disagreeing with Vos' exegesis quite a number of times, though Vos' Reformed Dogmatics is still good and worth reading.
Finally, I like to say that Bavinck's theological reflection is very devotionally warm and pastoral, more so than Berkhof, Vos, and Letham. This aspect is not a necessity for me since I don't expect a systematic theology genre book like this to be a Christian living devotional book. Just like how I don't expect my first-year biblical Greek textbook to be as devotional as John Bunyan's Pilgrim Progress. Nevertheless, this is a huge bonus for me. I especially like his theological reflections on eternal punishment.
