Kai's verdictA-tier. Close second to Cursor. If $5/mo matters, start here.A-tier for its niche. Different use case than Suno — SFX and loops, not songs.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
