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.A-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.S-tier for text-in-image. Use this for posters, Midjourney for art.
