You'll never get a definitive answer, NEVER. You omitted many others that deserve mention. The Zeke, Hurricane, P-47, Hellcat, Corsair, and others.
This should go in the Aircraft & Vehicles section.
If I had to choose, the Pony never would have been included. The Hellcat or Jug. After talking to a Jug pilot from WWII today at the Kalamazoo Air Zoo, I'd be torn with either.
