Three Image Generation AIs Compared — Midjourney vs. DALL·E vs. Stable Diffusion
I constantly need illustrations for blog posts and presentations, so I spent a week testing the three big image generation AIs with identical prompts. I fed each of them the same 20 prompts — things like "a traditional Korean hanok village in dawn fog, a cat on the rooftop, cinematic mood" — and compared the results.
Midjourney — the output looks the most like "art"
Given the same prompt, its lighting, color, and composition were the most striking. Its knack for turning even a sloppy prompt into something convincing is outstanding — when you need images with real visual flair, it's the first name to reach for.
- Pros: Overwhelming aesthetic quality, style-consistency features
- Cons: Effectively no free trial (paid subscription required), English prompts work better than Korean, rendering text inside images is still unreliable
- Best for: Designers, content creators, anyone for whom quality comes first
DALL·E — the easiest way to get started
You just type "draw me a picture of..." in the ChatGPT chat window and you're done — there's no barrier to entry at all. Being able to request edits conversationally ("make it two cats," "change the background to night") was a huge convenience in real use.
- Pros: Generate and revise conversationally inside ChatGPT, strong understanding of Korean prompts, follows prompt instructions faithfully
- Cons: Aesthetically a notch below Midjourney, tight generation caps on free accounts
- Best for: Beginners, everyday users who need illustrations for blogs and presentations
Stable Diffusion — ultimate freedom, but homework required
It's open source, so once installed on your own computer it's free with no usage limits. The freedom is unmatched — you can layer on add-on models (LoRA) to change art styles or fine-tune every setting — but installation and configuration come with a learning curve. You'll also need a graphics card (8GB+ of VRAM recommended).
- Pros: Unlimited and free (locally), best-in-class customization, relatively loose content filtering
- Cons: Tricky initial setup, trial and error needed before good results, demanding PC requirements
- Best for: People who enjoy tinkering, people who need to generate at volume

Verdict
After a week, my conclusion is simple. "If you need beautiful, get Midjourney. If you need easy, get DALL·E. If you need freedom, get Stable Diffusion." If, like me, your main use is blog illustrations, I'd recommend starting with DALL·E and subscribing to Midjourney later if the quality itch kicks in.
