Looks really impressive. For sure it would run circles around you in a dog-fight, but who does dog-fights anymore?
The Yanks proved it a long time ago back in WWII. There used to be a saying; "You can't out-turn a Zero". But they didn't have to out-turn them. They had faster planes. They could line up for a high speed attack run, hit them, and be heading off into the distance negating the superior maneuverability of the enemy.
Throw into the equation the eye-in-the-sky flying control towers, and the better electronic warfare that the Yanks have, and prolly not many modern air forces will be shaking in their boots.
