Kai's verdictA-tier. Best for fast prototypes. Competitive with Lovable — try both.A-tier for social/casual. B-tier for serious work. Good entry point.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
