Kai's verdict	S-tier. Market leader with reason. Start here for serious video.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.	A-tier in its niche. The only one that actually gets emotion right.
