Actully the Me163 is an incredible plane.
Basically, if fuel can endure, it's an ultimate fighting machine:
* it's wings have a nice large aspect ratio
* very light weight
* no torque at all
* very efficient combat flaps which deploy even at high speeds
* two of the most powerful cannon in the game
* power loading and wing loading is virtually whatever you want it to be
It's a plane that has no "Energy" troubles, since rocketry is way above any prop propulsion. Get into a tight spot? Accelerate away, or head straight up.
It's basically one of those planes which out run, out gun, out turn, out climb, out vertical, out accelerate, out deccelerate, out control and out everything else, except flight time.
