Best book on axiomatic set theory.

Question

Which is the best book on axiomatic set theory? I am interested in a book that is suitable for graduate studies and it is very mathematically rigorous.

Answer 1

I've found Kunen's book "Set Theory: an Introduction to Independence Proofs" to be very good. I've heard Jech's book is good also.

Answer 2

The best textbook on axiomatic set theory for Zermelo-Fraenkel Set Theory is "Axiomati Set Theory" by Patrick Suppes.
