I Tested 14 AI Coding Tools on 200 Identical Tasks. Here Are the Honest Results.

Most AI tool reviews are sponsored. The reviewer gets paid by the tool they review. I did something different. I ran 200 identical TypeScript tasks through every major AI coding tool with the same prompts and scored every output on 5 criteria: Code correctness TypeScript type safety Error handling completeness Architectural soundness Edge case coverage Here is what I found. The Rankings 1. Claude 3.5 Sonnet — 9.7/10 The best for complex TypeScript by a real margin. The key finding: Claude catches architectural problems before building them. In our tests it flagged design flaws 8/10 times. ChatGPT caught them 3/10 times. On simple tasks the gap narrows significantly. On system design the gap is large and consistent. 2. Cursor IDE — 9.4/10 Not an LLM but worth including — the in-editor experience changes how you work. Multi-file editing with full codebase context is genuinely transformative. $20/month. 3. GitHub Copilot — 9.2/10 Best value at $10/month. Inline autocomplete is still the b
