Do you include Field Quantization by Walter Greiner, Joachim Reinhardt, J. Reinhardt in this critique?
Yes. Now I admit that if you take one single volume of the collection and deal with a specific aspect of QFT, many detailed calculation can be found in Greiner's series (which in turn explains the fact that there are mistakes : since mistakes are unavoidable anyway, the more calculational content, the more mistakes too...). I am reproaching with for instance, the fact that "Relativistic Quantum Mechanics" is a separate volume to the one you quote. That is true, it is a different subject,
yet one could prefer books dealing with the
entire subject of QFT (and to a certain extent the standard model) rather than separate volumes often repeating each other and worse of all not even in a completely coherent fashion (the fact that those volumes have been written separately) I do have 6 volumes of this series, so I am not telling they are the worse books ever. I like them as a practical tool.
For instance, one has little hope to ever find a single book dealing with both formal aspect of QFT and nuclear models at the level of details found in Greiner's. But this series provides "only" detailed calculations, and with respect to QuantumDefect's original question, I would not recommend them to an undergraduate willing to get an historical overview. IMHO QuantumDefect should first concentrate on concepts. If you can go through "Quarks and leptons" by Halzen and Martin then you can postpone use of Greiner's series to specific later problems.
I'm looking for a book that hides no technique in its step from one formula to the next.
Do you even think it is possible really ? If you aim at reconstructing every little formula in details, it is going to take a while. It only depends on what you want and how fast you need it. If you aim at calculating Feynman diagrams and make quantitative predictions, then you can achieve this much faster than reading the whole Greiner's series.
In fact, I picture Greiner's series as a dictionnary, or an encyclopedia. I do not expect it to be read linearly, not only is it too much pain but it does not seem much useful to me.
Or what book would you recommend for an intro into the mathematical details of QFT.
For an intro, maybe
Quantum Field Theory of Point Particles and Strings. It is difficult to tell really, depending on what you want at which level.
