Kai's verdictA-tier for creators training custom looks. B-tier for general use.A-tier. Genuinely different vibe from Suno — worth trying both for a month.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier. S-tier if you self-host. The reason open-source image gen matters.
