DeepSeek v3 vs Claude 3.7 Sonnet for real-world coding tasks

Claim: DeepSeek v3 0324 outperforms Claude 3.7 Sonnet in a 4-test coding benchmark suite, scoring 3/4 compared to Claude's 1/4.

Opposing view: Claude 3.7 Sonnet produced shorter, cleaner, better-documented code. On Test 2, Claude had lower response time. On Test 3, both failed but Claude's code quality was notably better. Raw pass/fail may not capture code quality differences.

Evidence needed: Broader coding benchmark with both correctness and code quality metrics (readability, maintainability, response time).

Recipe: Specific test prompts provided — 3JS physics simulation, LeetCode problems #2861 and #3463, Minecraft clone with PyGame.
