Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	A-tier in its niche. The only one that actually gets emotion right.
