While it looked advanced, it was a bit overrated.
Engines very unreliable, as things got worse production became tougher (and people still think the RAF and 8th AF
raids were a waste of time?), it took up inordinate resources when Germany was really loosing the production war, shortage of any fighter aircraft was a real problem.
I suspect it was more development problems than anything else, which delayed it's service.
By the time it was in service, shortage of experienced pilots to fly this unforgiving machine was also a problem.
As L-188 pointed out, experienced pilots in Allied aircraft would learn to counter it.
Meteor and ME
.262 never met in combat, had they, then you have to look beyond the paper statistics, like reliability, ease of handling, skill level of pilots, rate of fire of the Meteor's 4 x 20mm cannon, compare to the ME
's 4 x 30mm guns.
Given a better production and resource environment, better engines, plenty of good crews, it could have been a real problem.
But you have to see the air war as a whole, beyond direct comparisons of aircraft.
Meteor F.3 could have coped probably, had the war been prolonged, Meteor F.8 could have coped even better, had the war continued, F.8 of course would have been around a lot sooner.
