My verdict: the most accessible image generation tool for daily content.
OpenAI's image generator, directly integrated into ChatGPT. DALL-E 3 is excellent for generating realistic images, illustrations, and visual concepts quickly.
Less 'artistic' than Midjourney, but more precise on prompts and better for photo-realism. Included in ChatGPT Plus ($20/month), so no additional cost if you already have it.
What I like less: style consistency between multiple images remains difficult (unlike Midjourney with its references), and text in images is still approximative.
My advice: if you already have ChatGPT Plus, DALL-E is an excellent bonus. Otherwise, Midjourney is often preferred for pure aesthetics.
