Co-speed on the deck in sustained flat turns, any spit, 109E & F, N1k2, F6f5, any F4U, just to name a few should be able to eventually drive around the circle on a P-38, or have enough of a smaller turn radius to gain angles. Some quicker than others. If they don't it is the pilots fault, not because the P-38 is 'excellent' at flat turns.
It's not about style.
