You don't know enough on the Tempest though. I'd probably say the Lighting was the best overall aircraft, between the two. I'd rather be in a Tempest if we're going low-level.
The Jug wouldn't stand a chance at low-level, it wasn't much of a fighter. Come on! It could take a beating but it couldn't dogfight with the best of them, although it was a P-47 that downed the first -262.
And the Mustang well, we're talking the -51D, it was good but as I always say it's major shining point was its range. Not it's dogfight ability.
