Chinese J20 vs USA Raptor F22

Seems that little by little USA is losing the leading edge on aeronautics, at least concerning combat aircraft, The new Chinese J20 fighters seems to be no less capable than the F22, with some features like double turbines, bigger in size and payload capacity, longer range etc., the J20 seems to be a serious contender for the worlds fighter aircraft supremacy, not counting also the Russian T50, if USA do not put care in development of new aircrafts and control the always out of controls costs, will lose its first place soon
