they're not asking for the best, they're asking for the greatest, if we're looking for the best it's the F-22 or summit like that, no, the greatest is something completely different, which was the best between the Sea fury and spitfire? the sea fury, which was the greatest? the spitfire, everyone's heard of the spitfire, P-51 and to some extent the -109, because they're legends, ask someone in Britain to name a fighter they'll say the spitfire, even though later fighters were better, ask someone in america to name a fighter they'll say the P-51, far from the best fighter but a legend all the same, in germany they'd say the -109, again not the best fighter but a great fighter, you see greatest doesn't mean best, greatness is a measure of it's legend..........
