I fly the Ki because she is a beast and takes a beating....it is great for lasting against the hoard. 
and it is far above the 51 and Dora as "fighters" 
Oh, so it is a *superior* fighter aircraft, one might even say *easier* to win an engagement with than a Pony or Dora, due to superior climb and turn?
You can't have it both ways, simultaneously claiming that your beloved Hayabusa is a superior fighter and then claiming it takes less skill to employ a P-51, Dora, or other unmaneuverable fast plane as a fighter. The two ideas are mutually exclusive.
