Weinberg is great for conceptual and historical understanding, a bit discursive. Frampton is more theoretical and concise and mathematical-abstract. No surprise that Dr. Glimm likes this best. Peskin and Schroeder is more detailed and practical. Schroeder was Peskin's graduate student, and the book is a result of years of teaching QFT to graduate students at Stanford. Freeman Dyson was the first to broach the question of the mathematical properties of the QFT perturbation series. He had advanced mathematical training that few physicists had or have. Physics is good for the soul, but so is mathematics. The former brings you in contact with the "real world"; the latter brings you in contact with clarity and rigor :)
