Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.A-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
