Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier. Close second to Cursor. If $5/mo matters, start here.	A-tier. Genuinely different vibe from Suno — worth trying both for a month.	A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
