Blimey no, they were just taking it on against the British far-east airforce, the Chinese airforce, the Ducht East Indish airforce, the Australian airforce, the US Navy and US Airforce at that time.
Bit silly to compare a late war Corsair to an early war design isn't it? The Zero got it's reputation early on in the war and well deserved in my opinion. They were not just fighting obsolete designs, but par example also did well against the British Hurricanes in Malaya. True, they soldiered on way to long, later US designs were quite a bit better, but in the well trained hands of the early Japanese pilots, in 1942, it was a lethal opponent.
