To be fair, the Corsair was the better fighter compared to the Hellcat. That's why it was the longest produced U.S. piston engine fighter - 11 years. Granted, the Corsair had some early landing issues on carriers which arguably limited deployment to Marine squadrons during the war (Navy pilots generally did not use land bases). Some of the longevity of production was likely due to the Navy's issue with the new jets, taking off/landing on a carrier. However, looking at a mid-1943 Corsair compared to a 1943 F6F-5, the Corsair was faster and had a superior roll rate than the Hellcat. Hellcat was better at diving. I'm not at all implying the Hellcat was a bad fighter, just that the Corsair was better. Both used the same R-2800 engine, but Vought's design of a slimmer fuselage, closer cowled engine, cooling ducts in the wing and flush riveting throughout made the difference. Just my humble opinion.
