It depends on the human and the AI.
I've seen ChatGPT pump out articles far better than many "native English" writers, but I find AI articles to generally lack personality, even when you try setting a tone in your prompts.
You can always try doing a mix by having an AI chatbot pump the articles out and re-writing them yourself. This way, the structure is there, you just need to check for inaccuracies and do some editing to make the content sounds appropriate for your readers.
