fw190D or Ta152
Unless you are planning on fighting at 20,000+ft or need long range the Fw190D-9 is better.
Ki84 or KI61
The only thing the Ki-61 can do better than the Ki-84 is dive. The Ki-84 is vastly superior.
Ki67 or Ju88
If you are hitting hangars then the Ju88A-4 is better, in all other cases the Ki-67 is very much better.
Ju87 or the Val bomber
The Ju87D-2 is better than the D3A1 in all ways other than handling.
Serenity is an idiot to even think of giving advice when he knows he is so obviously biased. If you can't separate your personal wishes from reality then you should refrain from pretending you know anything.
