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.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
