The superiority of an economic system is not defined by how much wealth it creates, but how much renewable value it spawns to yield sustainable strengthening of the evolution of humanity. And such sustainability can only be achieved with the proper implementation of freedom (away from its current totalitarian monism), a pluralism of freedom as the necessary ingredient to yield ever-evolving renewability.
Since none of us, in any country or on any continent in the world, have implemented such a relativity theory of freedom (with innate respect to freedom to each his own), none of our economic systems are contributing to the regenerative strengthening of the evolution of humanity as described above. Instead, we perpetuate quite the opposite with our rate-race for wealth.
So, the real question posed here is; which economic system in Europe or China is worse? Which I just answered with: neither.
