And it's far better in my opinion - ChatGPT actually creates its own prompts from what you give it and feeds those to DALL-E (you can see this by clicking on the images it returns and reading what the actual prompt was), although you can disable this by just firmly telling ChatGPT not to modify your prompt.

Additionally, the image generation itself is quite different. ChatGPT's DALL-E seems to create much more stylized images - much harder to get plain shots that don't heavily embellish your description.
