There is never anything that is superior all the time. The digram indicates that the "hinge" type is worse all the way to mach 1 then becomes better than the traditional one which is better up to mach 1. The traditional solution is particularly better between mach 0.6 and 0.9, so it is perfect for subsonic flight and dog fighter.
J-35A (and FC-31) is intended for airforce to whom supersonic performance is important, so it chose "hinge". J-35 is for navy to whom landing on deck performace is paramount, so it choose traditional approach.
F-35 is a monstrous compromise (缝合怪) and should never be used as reference in judging anything.
