Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Bet on this one — the Sparkpage format is genuinely new.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
