I read a comment by a former Japanese pilot who said that he was more afraid of the Hellcat, which seemed more maneuverable in a hot dogfight. But I'm sure the Corsair was pretty dangerous and it did well in air support in Korea. The Navy had, I think (?) withdrawn the Hellcat from first line units by then.
BUT...the Hellcat was replaced by jet fighters in the air superiority role and the F-4F was being used for ground attack, which may suggest that they felt the F-6F Hellcat was indeed a better fighter than the Corsair in air combat, so they got replaced by the next gen. of better fighters, Banshees and Panthers.
In addition the US, France and the Royal New Zealand AF used the Corsair. And the Royal Navy had them in service when the US Navy felt they were too unstable for sea duty. They relegated them to USMC air units operating from islands. The landing gear needed improvements to achieve US carrier service. The British were more desperate for suitable carrier fighters to bolster the Seafire that had longer range, so they adopted the Corsair and the Hellcat as well as the older Wildcat, which they initially called the Martlet, a kind of weasel.
The RN version had shorter wings, I think because the British carriers had smaller aircraft storage areas. As far as I know, the RNZAF Corsairs were the same as US versions, as they didn't operate from carriers. They replaced or augmented P-40's and Spitfires.
