What’s your Favorite Frederik Pohl novel, James E. Gunn?

My choices probably are pretty standard (although maybe I’ll be surprised by the final list): Gateway and The Space Merchants. Fred’s fiction is always an occasion, for those flashes of insight into the human condition as well as his great storytelling abilities and his skillful prose, I don’t think Fred (and Cyril) ever did better in Fred’s satire mode than his first, but Gateway is Fred at the peak of his mature powers and focusing on a more difficult target, the human heart rather than human folly. By the time Fred was able to write Gateway he had recognized that his skills at skewering human folly were a trap and he had moved on (at least most of the time). I’m looking forward to his new one.
