You know, you could try the following:
Go to the quick mission builder and set up a 16 vs 16 or even 32 vs 32 dogfight between Seafire and F4F. Make sure the pilot skills are the same for both sides. Hit fly, engage autopilot and watch the show.
I did a 16 vs 16 once, and all F4F got shot down in exchange for 5 Seafires. Not really a manoeuvring contest, more an overall comparison, but still a nice indicator.
And definitely hilarious to watch.
