Kai's verdict	A-tier in its niche. The only one that actually gets emotion right.	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	S-tier for builders. The right primitives. What Kai is built on under the hood.
