Both are strong assistants and both makers publish their own claims, which are not independent benchmarks. Try the same three real tasks in each: a draft edit, a prompt rewrite and a data summary.
These are the two best-known assistants. For creators the deciding factors are usually the writing style you prefer, whether you need built-in image generation, and price.
Give both the same rough image idea and ask for three detailed prompts; then give both a messy draft to edit. Judge which output you would publish.
