Definitely either the Fw190D9 or the P-51D.
The Dora has a better top speed (second only to the La7 down low, but better at most other altitudes) and roll rate, and its guns have better damage capability than the guns on the P-51D.
However the P-51D has guns that are easier to hit with, but do less damage, except right at convergence. And the Dora has a longer WEP time.
Both planes have lots of ammo, and plenty of fuel for long missions.
Basically its a toss up, with the two planes being effectively equal in most situations.
It just comes down to which you prefer to fly.
Kinggonad, the Ki61 as a Boom & Zoom plane? Have you been sniffing the av gas again?
