The aircraft has amazing flight performance; it’s sort of like a faster ta152h with the climb rate of the f8f. The real power of that thing does NOT reside on the armament since USA has only two less guns that still on four are far better, it’s on the fact that it simply does not suffer from compression nor thrust defficiency and can pull onto you no matter what scenario you place it onto. Everytime you see a j6k1 it always ends up with six or more kills for the sole fact it’s easily going to to catch up and nearly impossible to reverse since it pulls really hard.
The aircraft might just be a little BS for 6.0 but it’s not really “unstoppable”, just far better than people make it out to be.
