I would pick the Hurricane over the P 39 in either role. The P 39 achieves its maximum speed of 355 mph at only 13,000 ft, while the Hurricane IIC will do 335 at 20,000 ft, at 24,000 ft the two are both around 325 mph. In climb rates the Hurricane dominates with an initial climb rate of 2,700 ft/min and taking 8.5 minutes to 20,000 ft. The P 39 has an initial climb rate of around 2000 ft/min and taking 11.65 minutes to 20,000(P 39c). The Hurricane would have the advantage in maneuverability and turn rate. The only info I have on the dive rate for the P39 says that lateral control was quite similar to an early Spit I , with aileron control becoming quite stiff at speeds of 300 mph IAS,this would give the advantage to the Hurricane in high speed control.
