GitHub Copilot vs Cursor vs Windsurf vs Tabnine: I Spent $500 Testing Every AI Coding Tool (Honest Results)
After spending $500 and three months testing GitHub Copilot, Cursor, Windsurf, and Tabnine across real production projects, the results surprised me. The tool everyone recommends isn't actually the best value. Windsurf's Cascade feature delivered 82% faster multi-file edits than Cursor's Composer. GitHub Copilot's new Pro+ tier at $39/month costs double but doesn't deliver double the value.
