Kai's verdict	S-tier for coding. If you write code of any kind, this pays back the $20 in a day.	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.	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.
