Competition or Collaboration, which one is better for humanity/mankind's long-term progress?

Thorough history of mankind/humanity, we’ve seen all:
– the fall of communism, which supposedly a system which is based on collaboration
– and recently, the fall of capitalism, which supposedly a system which is based more on competition

So the question is: which one is better?
Or, could the BEST solution yet to be found is to combine both systems ie: competition and collaboration together?
