I prefer the P-47. The M model was faster than most mustangs, the N model had a ridiculous range, and, 8 Browning .50's is better than six. I don't know nearly as much as the rest of you, but it could almost certainly dive faster, and was probably tougher to kill and more rugged. The P-51 has it in high-altitude performance, and probably is a bit more manuverable, but I'd still take the Jug.
Plus, I think it looked so much more manly, I love radials.
