Conclusion:
SimpleJSON wins!
SimpleJSON wins with the smallest size, fastest speed and easiest integration
SimpleJSON is continuously optimized for Unity, with fast update, small size, fast speed and source code. SimpleJSON is recommended.
NewtonsoftJson was eliminated because of its large size and slowest speed. In principle, such a large class library must support more functions. Unfortunately, the existing project is not too complex json and cannot be tested.
LitJson is also small and convenient to use, but it has no advantage in speed.
