Kai's verdictS-tier for model-shopping. I use this for every prototype before committing.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier for designer-led sites. S-tier if animations matter.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
