Kai's verdictA-tier. Best for teaching a kid to code in 2026.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-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.
