My very subjective thoughts:
La-7: Very potent fighter. Most loathed yet still one of the most underrated planes of AH2. Not only high speeds were it really counts in the late war arenas (below 10k), but also deadly firepower and very good maneuverabilty. Only real drawback are the short legs.
Silly peer pressure is responsible for being largely a noob's ride, thus its impact in the MA is lower (K/D) than it's performance potential.
Spit-16: Sorry, I prefer the Spit-8, because it's more stable and a better gun platform (as long as you have ammo for the Hispano's). Still one of the best allround fighters in MA with it's combination of power and maneuverability.
Hurricane 2C: THE point and shoot plane. Easy to fly, easy to kill with in furballs & low alt base defense. Perfect M3 hunter vs the EW reset horde (you know who you are...

)
A6M5: Could be the best furballer... if it wouldn't start to burn just because someone is only looking at it.
The A6M2 lacks in firepower, ammo & engine power. The increased turning ability doesn't make up for it.
