Before (in China) and in the early part of WWII, the Zero had the advantage over most allied fighters. It had a powerful engine, was very light and maneuverable. The light weight came at the expense of no self-sealing gas tanks and no armor protection for the pilot. In addition, the skill level of the pilots was very high. Only the best Japanese graduated from pilot training, particularly the Navy pilots. The Zero or Zeke as it was later called, could out-climb and out-turn our fighters. To dogfight with a Zero was inviting death! Fortunately, we learned quickly to utilize the best features of our fighters to counter the Zero's advantages. You didn't dogfight, if you could avoid it. You picked a target, got above it if possible, made one diving pass and got the hell out of there! As thing progressed, and the F4U Corsair and F6F Bearcat came out, and the Japanese Navy lost a lot of their best pilots, even some of the improved Zeros were no match for the Marine and U.S. Navy planes and pilots. After the Mariannas Turkey Shoot, the major threat posed by the Japanese air forces were in the form of kamikaze attacks on our ships.
Happy, Healthy and Safe New Year, Pards!
