better yes, but 'much better'? the Ki84 has more ammo and some of the guns are centerline, which is a huge plus.
My collegues forgot to mention that the Ki can fly to hell and back with 50% fuel, while a spit will barely get off the runway
Hispanos/50's = peanut butter and chocolate.
Jap cannons/machine guns = Ike and Tina.
Center mounting is only awesome if all guns are mounted in the center.
Gas milage is irrelevant when not discussing the Toyota Prius.
