Not really, maybe you don't understand the context these terms are being used. Some planes accelerates better than others, for example, or turn better than others or retain energy better etc. The bottom line is, when you compare them and try to apply a strategy against the enemy you should know beforehand what kind of strategy to implement and when. In a K-4 I can go with 'turn and burn' against P51 and be safe or I can boom and zoom it and still be safe. Against the Spit, well, it's a different story, boom and zoom all the way, but that means you should be very good with the deflection shooting.
