AIs are better at creativity than us - specifically, better at generating new, creative ideas, as this is a matter of injecting some random noise to the reasoning process. They may be worse at filtering out bad ideas and retaining good ones (where "bad" and "good" are - currently - defined as whatever we feel is bad or good), but that's arguably a function of intelligence.

As the infamous saying of Eliezer Yudkowsky goes: the AI does not hate you, nor does it love you, but you are made out of atoms which it can use for something else.
