| Kai's verdict | S-tier for aesthetics. If you care how it looks more than how it's made, this wins. | B-tier. Use Claude + manual SEO thinking. Writesonic is fast but generic. | B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't. | S-tier for builders. The right primitives. What Kai is built on under the hood. |
