Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
