Regnat's book is much, much more technical and "engineeringlike", as aircraft monographs should be. E.g. it is mentioned in Classic's book that the Do 335 suffered from weak nose landing gear, but leaves it at that without analyzing why it was weak, what were the modes of failure and how it might have been corrected. I don't recall whether Regnat discusses this, but nevertheless such issues go unanswered in too many aircraft books.
