Kai's verdictA-tier for creators training custom looks. B-tier for general use.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
