ME 262 seemed to perform worse than conventional German aircraft.
While it is my favourite post-WWI fighter, as far as I know it wasn't significantly better, overall, than many fighters at the time. You must keep in mind that for much of its latter use it was primarily a ground attack aircraft as it was outclassed by post-war fighters (even piston engined).The F4U Corsair remained in production from 1940 to 1952. That was a huge accomplishment at the time of such rapid changes in tech. It was arguably one of the most capable fighters of its era.

Then you have to consider its purpose. While a Corsair could probably outfight a Mustang (all else being equal), a mustang was a far better bomber escort.

Eh? What piston engined fighters can outperform the Corsair? The only piston engined fighter in the same class (ie carrier based single engined multi-role fighter) that is at all comparable to the 4 and 5 variants in performance was the Sea Fury, introduced 3 years later, and while slower, the Corsair had superior range, ceiling, and bombload.
The Grumman bearcat for one.

"Unless we plunged nose first into the ground, we couldn't hurt the Thunderbolt". It could take the stress of any aerobatic maneuver. The pilots of the 56th Fighter Group grew to trust the fighter, knowing they could subject it to any demands of aerial combat.
After he arrived in England in early 1943, he saw his first Spitfire and compared it to the Thunderbolt. The differences were amazing. The P-47 was a giant, massive weapon; the English fighter was lithe and rapid, with the agility to dart in and out of battle. The RAF pilots warned the Americans that their huge Thunderbolts would be sitting ducks against the Messerschmitts and Focke Wulfs. They were wrong. The tough Thunderbolts more than held their own against the Luftwaffe.
One day in late June, 1943, Johnson's Thunderbolt was hit early in the mission and then helplessly subjected to an Fw 190's machine gun fire on the way home. You read about this famous story in the Robert S. Johnson article on this site. Somehow, incredibly, the P-47 absorbed this battering from the German guns and made it back. After the injured Johnson had landed his plane at the Manston emergency strip, he surveyed the damage it had taken, and later described the result in his autobiography, Thunderbolt!:
"There are twenty-one gaping holes and jagged tears in the metal from exploding 20mm cannon shells. I'm still standing in one place when my count of bullet holes reaches past a hundred; there's no use even trying to add them all. The Thunderbolt is literally a sieve, holes through the wings, fuselage and tail. Every square foot, it seems is covered with holes. There are five holes in the propeller. Three 20mm cannon shells burst against the armor plate, a scant inch away from my head. Five cannon shell holes in the right wing; four in the left wing. Two cannnon shells blasted away the lower half of my rudder. One shell exploded in the cockpit, next to my left hand; this is the blast that ripped away the flap handle. More holes appeared along the fuselage and in the tail. Behind the cockpit, the metal is twisted and curled; this had jammed the canopy, trapping me inside."
The airplane had done her best. Needless to say, she would never fly again.
Johnson had great success with the Thunderbolt, shooting down 27 German planes over Europe while flying the rugged fighters.
how bout the P-47D?
F8F and others introduced at the end or just after the war?What piston engined fighters can outperform the Corsair?
More late war variants of the P-51 were built than early. And their range was far more useful to the USAAF than any advantage in other characteristics. They were the ultimate bomber escort in WWII, which quickly became the primary role of USAAF fighters.More Mustangs were built. And more built early in the plane's history. But that was in part because of the mistake on the part of the US Navy in thinking that the Corsair's landing characteristics made it not their first choice for a carrier fighter.
Which is exactly where perspective comes in. You may want one set of characteristics, and I may want another.The Thud's a lot bigger and heavier, giving it superior dive speed, firepower, and damage absorption, while the Corsair is faster, longer ranged, faster climbing, and can turn circles around the Thud.
Bearcat's a dedicated interceptor with weaker armament
true, but you did ask for "any piston engined fighter"
Weaker armament how exactly? Post-war Corsairs and Bearcats both had four 20mm cannons.
Anyway the bearcat was intended to be an interceptor but like a lot of designs they usually find their best niche is outside of the box that it was meant for. Just like the corsair's niche was found to be ground pounding rather than air superiority. The bearcat was arguably one of the best dog fighters ever, was one of the fastest production piston fighters of all time and remains unbeaten in climb rate.
