Reportedly, when a certain fighter group switched from its beloved spitfire (IIRC) to the P-47, CO advertised its fantastic diving abilities.
One of the top dogs flew it, climbed down after the flight, came to CO and said "it's good that she can dive, because she sure can't climb"
I think she can handle a turn contest vs 190s, at least vs AI.
Against a 109, she's in the same situation as the F4 was vs the Zeke, defensive tactics can delay the inevitable,no more, if the 109 jocks are any competent.
Now she doesn't need a full fuel load most of the time, and keeps her efficiency at very high altitude too.
