Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Useful for first drafts. v0 is the better bet for shipping code.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.
