The P-47N is a little better than the Pony in a head-to-head fight in AHII right now, if the Pony doesn't have too much of an initial advantage. The Jug rolls better, is deadlier on the snapshot, turns better with flaps, and is generally more stable trying to turn at low speeds. This maneuvering advantage for the Jug is HIGHLY inaccurate, but this is what we've got.
As long as you keep the Jug light that is. The P-47 can carry a ton of fuel (With 50% fuel it will fly as long as the D-40 does on 75%...with 75% the N flies for nearly 45 minutes!) At 50% fuel with the 267rpg 8 gun package, you're okay.
The disadvantage of the Jug here, is of course it only matches the P-51D's engine power for 5 minutes. Without WEP, it is well below the Mustang in top speed and climb until very high alts. Whereas the Mustang is running along at some truly screaming speeds in normal cruise configuration. This arguably makes the Mustang equal or better than the P-47 for the general MA melee.
