Sax, if you fight a P-47N the way it wants you to then you might as well give up right then and there. If you manage to get a new pilot then OK, but that holds true with most planes as well.
Don't be delusional. At 30k, the F4U-4 is as capable as the P-47N and below 25k, it completely owns it.
Think about this: 453 mph at 27k... And, it'll fly circles around the P-47N should it attempt to maneuver with it. The P-47N may be the best fighter above 32k, but the margin over many other fighters is small.
At lower altitudes, the P-47N is out-performed and vulnerable to many types.
In comparison, the F4U-4 is the equal of the La-7 on the deck. It'll out-turn a Spit16, chase down a Dora, and completely dominate the Tempest. As an overall fighter, the P-47N isn't in the F4U-4's league. Seriously, nothing else really is either.
