Kai's verdictA-tier. S-tier if you self-host. The reason open-source image gen matters.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Genuinely different vibe from Suno — worth trying both for a month.
