Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier. Niche but beloved. If you've outgrown Notion, try this.
