Round 1: Writing Quality Claude Wins (Barely)

We asked both to write a 1,000-word blog post on "5 Ways AI Will Change Small Businesses in 2026" with no other instructions.

🤖 ChatGPT Plus

Well-structured, clear headings, good SEO flow. Slightly more generic — read like a polished article but lacked deeper insight. Required minimal editing. Score: 9.4/10

🧠 Claude 3.7

More original angles, richer examples, and a more distinctive voice. Felt like it was written by a thoughtful human. Required almost zero editing. Score: 9.5/10

Round 2: Coding & Debugging Claude Wins

We gave both a buggy Python web scraper with 3 hidden errors and asked them to debug and improve it.

🤖 ChatGPT Plus

Found 2 of 3 bugs immediately. Missed a subtle async error. Code was clean and well-commented. Fixed the third bug after one follow-up. Score: 9.2/10

🧠 Claude 3.7

Found all 3 bugs on the first pass, plus flagged 2 additional inefficiencies we hadn't noticed. Explanation was clearer and the refactored code was more maintainable. Score: 9.6/10

Round 3: Long Document Analysis Claude Wins by a Mile

We uploaded a 120-page PDF report and asked both to summarize key findings and identify 3 contradictions in the data.

🤖 ChatGPT Plus

Hit context limits with the full document. Processed only the first ~60 pages. Missed contradictions in the second half. Had to split the doc into 2 sessions. Score: 7.8/10

🧠 Claude 3.7

Processed the entire 120 pages in one session with its 200K token context window. Found all 3 contradictions plus a 4th we'd missed. This is Claude's biggest advantage. Score: 9.7/10
