Kai's verdictB-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.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. S-tier if you self-host. The reason open-source image gen matters.
