USSR economic system is called socialism, which is a step in direction to communism. Given that this might be a particular flavor of socialism/capitalism, nothing significantly different was tried experimentally, so to say.
I also disagree with the certainty of you last statement claiming that a better system exists, which I assume you mean communism. Existence of such system on paper does not mean that it works in practice. It is possible, and in my opinion is very likely that particular features of human brain, of human psychology makes the system relying only on altruism to be less effective that the system that relies also on material interests.
It is plausible that in future, with different level of economic development, and with possibility to directly modify brain pathways (or transferring to silicon all together) the situation can be different and better system may exist. But with current biological humans and present development level? I seriously doubt that.
