Do you have any data and reports of the Meteor.
I've seen one doing rather nice maneuvers and seeing was just a bit of it - the engine sound is really funny.
Anyway, it did a very slow, low alt loop, so I'd imagine that thing could probably turn well also.
As for the guns, well, a matter of choice. I mean a 262 can kill you with only 1 shot!
But it can not catch a 262 - AFAIK the 262 is a good bit faster. So the Meteor sort of sits inbetween the prop fighters and the 262.
I have very little data on the ROC and the roll rate, - the 262 performs those well. And dive speeds limit.
Well IMHO, if the 262 is here as well as the 163, - the question is about the Meteor and the Heinkel jet.
