Kai's verdictS-tier for speed. When latency is the product, start here.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
