The F4F-3 because it was the model of the Wildcat that had the best climb rate until the advent of the FM-2. If the USN had kept the -3, or better, kept a mix of folding wing and non-folding wing F4Fs using the former for Escort and the latter for CAP, I believe Hornet would have survived WWII or at least the Santa Cruz battle. The FM-1 appearing in September 1942 should have been a better plane than the F4F-4 if it used a reduced ammo load, and would have therefore possessed a better climb-rate. The USN CV's needed a decent climbing fighter as an interceptor and the F4F-4 was a step backward. By the time the FM-1 came into being, the F6F filled the bill nicely. All F4Fs were adaquate fighters (each version having some disdavantage) but, in general, terrible interceptors. This was less true of the -3 than the others until the FM-2.
