Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for open-source model APIs. The default in this space.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for speed. When latency is the product, start here.
