Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.S-tier in the agent category. The first one I'd give to a non-technical friend.
