Kai's verdictS-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
