I went back and read your question and thot about it this time.
I'm going to go with the D3A1
sounds like a joke answer but at 200 start, you roll 180 and pull hard you are now operating at super low speed.
all the turn fighters have various rates of roll but the difference I found was the ability to drag their nose under (pulling hard) without stalling into non-manuverability.
The Val will roll slow but the move of the nose from pointing away from your target to pointing to him (the 180 of the turn and not the roll) is the quickest.
what I'm saying is that the varience in the roll rates isn't as big a gap as the varience in the pulling under turn.
And the Val Shines in this area. Minimal stall you can fairly yank your way thru it and it doesn't gain much speed on the down turn driving the turn radius wide.
may sound like a dumb answer but that's what you get from a B&Z plane driver

btw this is without consideraton of flaps because that wasn't listed but would greatly help the move in most planes imo.
