Kai's verdict	B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic.	B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.	S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.	A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
