For the early jet fighters you can only match their performance against the Me-262 and the MiG-15 as the US & UK ones never saw action against each other in 3 party air forces IIRC.
I knew (quite well) two RAF officers who had flown Meteors (Australian) and F-86's (US) against MiG-15's in Korea
They thought that an F-86 in the hands of an "average" pilot could beat any MiG-15 most days but that an "average" Meteor pilot would be in trouble against an "average" MiG 15 pilot most days
