... that today the P-51 and the Spitfire are probably the most famous planes of WWII?
Coincidence? 

Then you have the P-47, P-38, 109/190, and Zero, also strong in the fame department, thus they will surely see more usage than the La7 or N1K...
Oh wait, my train of thought just ran off a cliff.
BTW Anax, you can NOT at this point make a bid for perking the P-51D without being a hypocrite. The same Z-scoring data you've been playing with and using as a reason to perk the Spixteen I saw a long time ago, and it demonstrates the mediocrity of the P-51 and why if anything it probably needs a slightly higher ENY.
