Kai's verdictA-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier. Category leader. Nothing else is close yet.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
