Hi, I'd like to ask recommendation for a QFT book. I have seen several other recommendations on this forum, but hopefully I'll provide enough info so you guys can have more specific advice. Background: QM (Griffiths, some parts of Sakurai), GR (Carroll), some residue calculus/lorentz-poincare group. I am currently using Zee/Peskin/Srednicki, but I am debating to which one to use as a main text (which I read very carefully) because I am moving very slowly if I read all of them well. This is for self-study. I like the problems in Peskin, but I don't like his presentation at all. On the other hand, I don't like the problems in srednicki, especially his notation, but his derivations are more elegant and compact and detailed.
