Do you think Communism would be economically beneficial if it got into full-swing?

In regards to capitalism and communism, which type of government has been the most economically beneficial. By economically beneficial, I mean boosting the health of the economy, generating the most wealth and attracting healthy, competitive businesses. I understand that communism never really got into full swing, because of rampant corruption, but I was wondering what communism would be like if it got into top gear. Appropriate prices being paid out for medium jobs. Lower prices for easier jobs, higher prices for the coal miners. Just general equality of work/pay ratio. Capitalism is good because it encourages free trading, Democracies are statistically more beneficial because of countries like Saudi Arabia, who rake in billions of dollars just because of their oil, even though their ovarall economic health is poor. I was really just wondering if communism could ever be the most beneficial?
