How We Tested
We paid for all three subscriptions ($60/month total) and ran each through 15 real tasks across five categories: writing, coding, analysis, image generation, and reasoning.
Pricing: All Three Charge $20/mo
| Plan | Price | Best For |
|---|---|---|
| ChatGPT Plus | $20/mo | General use, ecosystem |
| ChatGPT Pro | $200/mo | Power users, o1 access |
| Claude Pro | $20/mo | Writing, long docs |

Writing Test: Claude Wins
We gave each tool the same brief: "Write a 1,500-word blog post intro about sustainable packaging for a B2B audience."
ChatGPT produced clean, structured copy but with telltale "in today's fast-paced world" filler phrases.
Claude produced prose that read like a senior copywriter wrote it. Sentence variety was best; the AI-tell was almost zero.
Gemini produced accurate, well-structured copy but slightly more formal/robotic than the others.
Winner: Claude. The prose felt human.
Coding Test: ChatGPT Wins
Same Python task: "Build a Flask API with JWT auth and a /login endpoint."
ChatGPT produced working, well-commented code-codex-codex-codex)-codex)](/posts/best-ai-code-assistants-2026)](/posts/best-ai-coding-tools-2026-cursor-windsurf-claude-code)-codex on the first try. The included test cases worked.
Claude produced the most elegant solution but added an unnecessary dependency.
Gemini produced working code-codex but with one security flaw (used MD5 instead of bcrypt for password hashing  a real issue).
Winner: ChatGPT. Most reliable, best debugging when we asked for fixes.
Image Generation: ChatGPT Wins
Only ChatGPT and Gemini do images natively. Claude relies on a separate subscription.
ChatGPT (DALL-E 3)  excellent prompt adherence, handles text in images. Gemini (Imagen 2)  beautiful images, weaker text rendering.
Winner: ChatGPT.
Reasoning Test: Mixed
Math word problem: "A bat and ball cost $1.10. The bat costs $1 more than the ball. How much is the ball?"
All three got it right (10 cents).
Logic puzzle (Monty Hall variant)  all three got it right with explanation.
Hard reasoning task: "Plan a 7-day trip to Japan for a family of 4 with a $4,000 budget." ChatGPT produced the most practical plan.
