The Ki-84 is by far my favorite AH ride.

Close second is the P-38L. Great for attacking and a fine dogfighter.
Favorite vechicle is the Tiger. I always want this biggest gun in a tank fight.
I have a handful of rides I use for specific needs.
La7 for base defense when you have to up from the next field and punish the vulchers.
N1K-J to fight your way up and out of the vulch and make life hell on the red guys. Spit 16 not too bad for this and I love its roll rate but I prefer the N1K.
110G when ord is down and a town or V-base needs to be dead. Its very effctive against other aircaft who take her too lightly as well.
C-Hog when Im at sea. The 4 Hispanos are like crack and are second to none for "base suppression CAP".
And finally the Hurri IID for tank busting. Its overlooked due to the IL2 but she is a great tank buster. Its shreds Panzzers and it will take out a Tiger. Doesnt seem to phase the T-34 for some reason but I can live with that.

btw, thats Krustys kick bellybutton new Ki-84 skin.
