| Kai's verdict | 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. | A-tier in its niche. The only one that actually gets emotion right. | S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing. |
