Kai's verdictB-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.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. The right answer if you want open-source + terminal-native + model-agnostic.
