Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for academic research. Nothing else comes close for systematic reviews.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
