Kai's verdict	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.	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.	A-tier. No reason not to use it if you're on Figma. Not worth switching for.
