For pure turn fighting EW planes dominate; A6M2, Bf-109E4, C.202, F4F-4, Ki-61, Sptifire Mk I. I might have missed a few.
For pure B'n'Z the FW-190 series in general and the D9 in particular win over the P-51D due to control responsiveness at extreme speeds (600 mph).
The fact is that most fights transition between these into and through middle ground opening the field to A's, B's, C's, F's, P's, Spits and others of all shapes and flavors.
