3–5 Feature Rounds: My Real-World Tests
Round 1: Prompt Adherence – “A cyberpunk cat wearing a leather jacket, sitting on a neon throne, drinking a glowing soda, 8K, cinematic lighting”
DALL-E 3:
First generation: Perfect cat, leather jacket, neon throne, glowing soda. The soda had a distinct neon glow. The lighting was cinematic. But the cat’s face was slightly too human-like (uncanny valley). Second generation: Better cat face, but the jacket lost some detail. DALL-E is incredible at understanding complex prompts—it didn’t miss a single element. However, it struggled with “8K” (output was still 1024x1024) and the cinematic lighting was good, not great.
Leonardo AI:
I used the Realistic Vision v5.1 model with “cinematic lighting” as a negative prompt? No, I added “cinematic lighting” as a positive prompt. First generation: The cat looked photorealistic. The leather jacket had texture. The soda glowed, but the neon throne was more of a simple chair with neon lines. The lighting was moody and dramatic—better than DALL-E’s. However, the cat’s paw was holding the soda in an odd position (anatomical issue). Second generation (with negative prompt “deformed hands”): Much better paws. Overall, Leonardo gave me a more artistic, high-fidelity image, but required a few tweaks.
Winner: DALL-E 3 for prompt adherence (no missing elements). Leonardo for aesthetic quality.
Round 2: Editing & Control – “Take the above image, remove the soda, and add a glowing sword in its place”
DALL-E 3 (via ChatGPT Plus):
I highlighted the soda area and typed “replace with a glowing sword.” DALL-E understood the context instantly. The sword appeared in the cat’s paw, glowing with a blue aura. The rest of the image remained identical. It took 8 seconds. Flawless.
Leonardo AI:
Used the Inpainting tool. I painted over the soda region, selected “image-to-image” with a prompt “glowing sword, held by cat.” First attempt: The sword was placed next to the cat, not in its paw. Second attempt: I used a more precise mask and added “in the right paw” to the prompt. The sword appeared, but the cat’s arm looked slightly distorted. The background also shifted a bit (color change). It took about 40 seconds total.
Winner: DALL-E 3. Faster, more accurate, no background bleeding.
Round 3: Style Versatility – “A watercolor painting of a dragon flying over a castle at sunset, dreamy, soft colors”
DALL-E 3:
Selected the “Watercolor” style preset. The result was a beautiful, soft watercolor dragon and castle. The colors blended nicely. However, the dragon’s wings looked a bit like smudged paint (too abstract). The castle had correct perspective. It felt like a real watercolor painting, but lacked fine detail.
Leonardo AI:
Switched to the DreamShaper v8 model with “watercolor” in the prompt. First generation: The dragon was detailed, scales visible, but the watercolor effect was weak—it looked more like digital art with a filter. Second generation: I added “watercolor texture, paper grain” to the negative prompt? No, I added them as positive prompts. The output improved, but still not as authentic as DALL-E’s watercolor. However, the dragon’s anatomy was better.
Winner: DALL-E 3 for authentic style rendering. Leonardo for subject detail.
Round 4: Speed & Iteration – “Generate 5 variations of a futuristic cityscape at night, each with a different color scheme”
DALL-E 3:
I typed the prompt and asked for 5 variations. Each took about 10 seconds. All 5 were ready in under a minute. The color schemes (neon blue, purple, red, green, gold) were accurate. But all images were 1024x1024, and the architecture looked similar across variations (same building shapes, different colors).
Leonardo AI:
I used the Prompt Magic feature with “futuristic cityscape, night, [color] lighting” and generated 5 images one by one. Each took 20–25 seconds (free tier). Total time: ~2 minutes. The variations were more diverse—different building styles, camera angles, and even weather (one had rain, another had fog). The resolution was 1024x1024 (free tier), but I could upscale later.
Winner: DALL-E 3 for raw speed. Leonardo for diversity of output.
Round 5: Realistic Portraits – “A close-up portrait of a 40-year-old woman with freckles, green eyes, and a subtle smile, natural lighting, photorealistic”
DALL-E 3:
First generation: The woman looked good—freckles, green eyes, smile. But the skin was slightly too smooth (plastic-like). The lighting was soft, but not truly natural. Second generation: Better, but still had that “AI” sheen. DALL-E’s photorealism is decent, but not top-tier.
Leonardo AI:
Used Realistic Vision v5.1 with “photorealistic, 8K, natural lighting, skin texture.” First generation: The woman had visible pores, freckles that looked real, and the green eyes had depth. The subtle smile was natural. The lighting was warm and soft. It was almost indistinguishable from a real photo. I had to double-check if it was a photograph. Second generation: Even better—the hair had flyaway strands.
Winner: Leonardo AI. Unquestionably superior photorealism.

- Free tier – 150 tokens/day (about 50 images) is generous.
Cons:
- Steeper learning curve – Need to understand models, negative prompts, and settings.
- Slower – Especially on free tier. Paid plans are faster but still slower than DALL-E.
- Inpainting can be finicky – Background changes, anatomical issues if not careful.
- Prompt adherence varies – Sometimes misses elements unless you use specific syntax.
- Token system can be confusing – Different actions cost different tokens (e.g., upscaling costs extra).
- Commercial license requires paid plan – Free tier uses CC license (attribution required).
Final Verdict
After three months of daily use, here’s my honest take:
Choose DALL-E 3 if:
- You’re a beginner or casual user who wants quick, reliable results.
- You need fast iteration for social media posts, blog headers, or concept art.
- You value perfect prompt adherence over absolute photorealism.
- You want seamless inpainting/outpainting without technical fuss.
- You’re on a budget and ChatGPT Plus already covers your needs.
Choose Leonardo AI if:
- You’re a serious creator, designer, or artist who needs maximum control.
- You require photorealistic portraits, product shots, or high-res prints.
- You want to experiment with different styles (anime, fantasy, 3D) and fine-tune outputs.
- You’re willing to invest time in learning models, negative prompts, and ControlNet.
- You need commercial-grade images with upscaling to 4K.
My winner: Leonardo AI.
Why? Because for my workflow—creating realistic product mockups, character designs, and high-res prints—Leonardo’s control and quality outweigh DALL-E’s simplicity. Yes, it’s more work. Yes, it’s slower. But the final images are consistently better. DALL-E is like a friendly assistant that gets 80% of the way there instantly. Leonardo is like a professional tool that takes you to 95% with effort. For paid work, that 15% difference matters.
That said, I still use DALL-E 3 for quick drafts, social media posts, and when I need a specific prompt executed perfectly on the first try. They complement each other. But if I had to pick one tool for serious image generation in 2025, it’s Leonardo AI.
