Maybe one similar comparation- Corsair and Lavockin La-7 have similar performance, regards to the top speed at mid level [were the most fight encountered]. In the East front Soviet pilots did not have any problem to wipe of any variant of Fw190 and this plane definitely rule the sky. I am sure that Corsair deployed in same number as other US fighter could perform excellent.
US fighter are massive and with very strong engines, much more power then the Germans. This mean more fuel consuption but US did not have that problem with fuel as German did. This mean that they should not have problem with wing load as well aramament was placed in wings. Wing armament mean that gun fire is desipersed in wide area and less chance for enemy to escape from being hit. German fighter have central armament and this mean more devastating efect on target but in other hand need more skilled pilot to do that. And Germans did not have it.
Just to note some Mustang tactics against Me262- they start fire from very large distance on Me262 and Germans are usually start to swing and turn to keep away from bullets. This action slow down the speed and Mustang get in much closer distances and get the jet into the sight and down it.
Germans are lucky that US did not deploy enough Hellcats and Corsairs there

Mustangs and Lavockins was far enough for them to wipe them off from sky. Off course- regards to all fighters and brave pilots who fight this evel force which wanted to role the world [best regards to all PZL fighters, Ikarus fighters, Rogozarski fighters, Dewoitine, Morane, Fokker, Yak, Polikarpov, Koolhoven...]
Cheers
