Kai's verdictA-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.A-tier. Genuinely different vibe from Suno — worth trying both for a month.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
