I can't answer for Herbert's book, but I can tell you how this one compares with my book

This is a translation of one single source, accompanied by the author's interpretation of how it all works. Both the translation and the interpretation are a bit dated - mainly because Lindholm was one of the first to publish on the subject, so it is still of interest, but there are maybe some other more up-to-date works on the subject.
My book, the
AHA German Longsword Study Guide, is a broad look at several sources, trying to piece together where we get our information about each different technique and concept. Therefore, it's more of a general synthesis, describing what the sources (in general) say about the different elements of the longsword system. The translations are my own, and to be honest there are probably better translations out there, and there is very little by way of interpretation in the book - the purpose is to show the information that we possessed on the subject (in 2013) so that people could make their own informed decisions about how to interpret everything. So, a slightly different purpose!
Naturally, I would recommend my book if you have an interest in the scholarly side of things, or if you are interested in the sources from which we draw our information. If you are more interested in having an interpretation of the system to work with and learn, then Lindholm's book is a reasonable start, as long as you are aware that the information and interpretation are somewhat out of date.
