You are truly an idiot of epic proportions.

You might want to consider not wasting bandwidth further with pointless, gratuitous insults that really say nothing bad about the person they're directed towards but do suggest that your mother raised you without any manners and you still need to grow up. Just a suggestion, of course.
There is no "best feature" of Soviet-sytle Socialism. None.
Sure there is, several of them in fact. Full employment, relatively narrow income gaps, high levels of economic security. If the system had literally NOTHING going for it, the Russian people wouldn't have supported it for more than seventy years.
In spite of which it didn't compare favorably to the social democracies of western Europe and (at that time) the U.S., any more than laissez-faire capitalism did (although for different reasons). So I'm certainly not recommending that system. But to claim that it had no beneficial features at all is nonsensical hyperbole.
