Kai's verdictS-tier for text-in-image. Use this for posters, Midjourney for art.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for model-shopping. I use this for every prototype before committing.
