Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
