i don't know...
we already have the me163 and 262 why would be there another jet?
pretty much the same though...
No it isn't.
"Comparison with the Me 262
The Gloster Meteor entered service just after the Messerschmitt Me 262. In July 1944 the experimental unit Erprobungskommando 262 (Test Command 262) began to fly experimental interceptions of high flying Allied reconnaissance aircraft. On 25 July one of their Me 262s clashed with a RAF Mosquito, which escaped, allowing its crew to report their first encounter with a German jet. The first operational sortie of the Gloster Meteor came two days later, on 27 July.
The Gloster Meteor can claim to be the first jet fighter to enter operational service, while No.616 squadron of the RAF was the first operational jet fighter in the work. The first fully operational Me 262 squadron, Kommando Nowotny, was not formed until September 1944, under the command of the famous ace Walter Nowotny, flying its first operation on 3 October.
The Me 262 was a more capable aircraft than the wartime versions of the Meteor. Its top speed of 540mph was 50mphs faster than even the Derwent IV equipped version of the Meteor III. However by the end of the war the Meteor IV was almost ready, and had the speed to match the German jet. On the plus side the Meteor was much more reliable than the Me 262, which suffered from famously unreliable engines."

http://www.historyofwar.org/articles/weapons_gloster_meteor_WWII.htmlDifferent guns, different engines, different speeds, different abilities. you just can't compare the two by saying they are both jets from WWII.
BTW, the ME163 is a ROCKET. That is all.
