Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.S-tier inside Photoshop (Generative Fill). B-tier standalone.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
