Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.
