If you're just flying eny+20 ur missing out on Ki-84 (eny 15).
It's the most fun plane for me as you can pull some wicked reversals on people and the guns are quick firing (makes em one turn shots efficient). You can pull some beautiful vertical manuevers on spits and rip their wings off, leave them scratching their heads! Calling out that you're a zero dweeb (yea, when you make some of the MA donkeys believe ki-84 = zero in turning youve succeeded). Also it's kryptonite to K4 drivers who go vertical, cause its climbrate is enough to make life difficult for em.
Oh and it has a kamikaze escort skin. Sure, spit9 has the pink skin but the novelty wears off same as with wearing pink thongs.
