That is just the 8th Air Force. I don't the numbers of the 15th Air Force, 9th Air Force, or 2TAF to hand, but German jets and rockets made little impact on Allied operations. The same would have been the case if they had been available in June 1944, or February 1944.

all in P-51Ds, all with camera gun confirmation - they would have been probable kills without it.
If your aircraft is 100mph faster than the fighters it has to face in combat - and it still gets shot down in droves - it's probably not very good.
However, no Gloster Meteors were ever shot down by any enemy aircraft during WW2.
