Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Genuinely different vibe from Suno — worth trying both for a month.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
