Kai's verdictB-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.A-tier for social/casual. B-tier for serious work. Good entry point.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
