Kai's verdictB-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier for model-shopping. I use this for every prototype before committing.
