I feel this depends heavily on what you are trying to achieve and the environment you are working in. For example growing in Steem I would argue is about 50/50 creativity and teamwork, your creativity wont be seen without networking and networking is pointless if you have no creativity to put on display.

however in a one person art startup like an etsy store creativity becomes overwhelmingly more important.

Then on the other end of the spectrum working for example a tradition job in IT support teamwork is far more important than creativity.
So in conclusion this is an interesting question as I don't think there is a single easy answer.
