Kai's verdict	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.	A-tier in its niche. The only one that actually gets emotion right.	B-tier. Still early. Manus is more flexible for less money.
