Draw your own conclusions. I'm very impressed with the F4U-4. Extremely balanced performance. Likewise, the P-38J/L demonstrates excellent climb and startling acceleration at 20,000 feet.
You can also see how badly the Tempest's performance degrades as altitude goes up. Likewise for the La-7.
All speed data using E6B for accuracy. Timing via digital stop watch.
75% fuel at takeoff, fuel burn set at 2.0 per the MA.
Acceleration: Altitude, 25 feet. Adjust power to steady at 200 mph. Go to max power (with WEP where available). Time needed to attain 300 mph.
Results in seconds, no rounding.
